We are now four days post-attack,
and as of 9:00am this morning, the death toll now stands at 18.
Working hypothesis?
A targeted attack by an Islamist group.
We found this.
Improvised detonator. ISIS's go-to det of choice.
My gut tells me we're dealing with sophisticated bombers,
not some amateur Islamist who's got a grudge.
Just stick to what you know. OK?
When it comes to explosives, I'm the expert. I know what I saw.
You were right, Wash.
They abandoned their factory
and planted evidence to make it look Islamist. That stain proves it.
How the hell are the bombers getting military-grade explosive?
You working? Is he bollocks!
It's just tough at the minute.
It was always "my team needs me" with Nut. Like we didn't.
IED left centre!
Battery pack explosive taped underneath the desk.
All set.
The device was found by a worshiper in the mosque.
Everyone's been evacuated. Islamists don't bomb mosques.
There's... like a bag.
Was anything attached, like a mobile phone or a watch?
Yeah, yeah, a watch.
There's an explosive device triggered by movement.
Just stay really, really still, OK? Get out now!
MUFFLED SHOUTING Get me out of here, please.
SIRENS
Please help!
Help! Please help!
Help!
Please get me out of here!
I need those people taken back to the second cordon,
an extra 50 yards at least.
Any police officer on this side of the cordon
needs to be wearing a lid.
MUFFLED SHOUTING
OK, listen to me. I know it's scary.
I'm a bit scared,
but it's gonna be fine. I'm just gonna get some tools out,
so just stay really still and really quiet, yeah?
Please get me out of here. I don't know what's going on.
Can you get me out? Still and quiet.
SIRENS BLARE
You've got 90 seconds, Lana! Hurry!
Please... If you can hear me, you need to hurry!
Please get me out of here!
No, no, don't leave. Don't leave, please. Keep calm.
Please, please! Please will you just shut up?!
Please try and stay calm. Please help me.
Help me, please. Please!
My hands are slipping.
MAN CONTINUES SHOUTING
Lana!
Lana! Lana!
Please help me. Please be quiet!
SHOUTING CONTINUES
30 seconds.
We've got 30 seconds.
I'm nearly there. Lana, please.
I'm nearly... Danny, get off.
I'm nearly there. God help me.
Please, God, help me. Don't leave. I'm nearly there. Get off!
Let's go. Let's go. Get off!
SHOUTING CONTINUES
I don't wanna die!
Hard cover! Hard cover! Hard cover! Hard cover!
Get down!
SIRENS
'EXPO has concluded search for secondaries. Site secure.'
EXPO 2, Received.
I'm sorry, Lana.
Let's go.
We need that audio file traced.
Ask Security Services if they've got any updates
on our priority targets.
We've got access to all the best assets,
in terms of surveillance and technical resources.
Let's use them, please.
I'll need CCTV from every camera within five miles of that mosque.
Now, now more than ever, we're under pressure to get a result.
I want the suspect list cut down.
We can eliminate any extremist in custody
or already under surveillance as persons of interest, yeah?
Right, everyone.
Thank you all for working through the night
on the incident at Amburiq Mosque.
This situation now takes priority for all counter-terror units.
It's almost 2:00am. I have an ELG meeting in five minutes.
Give me something to bring.
Ma'am, this recorded message was sent to us
and every single major news station, on an encrypted service.
COMPUTERISED VOICE: 'This is payback for Westhaven.
'Amburiq was the start of the fightback.
'We call on the white race to take up arms. We are the Crusaders.'
The audio source is heavily encrypted.
Tech are giving us everything they have, but it might be a dead end.
I'll get GCHQ to apply a little more pressure on the servers.
Any evidence at the scene confirming their involvement? Hi.
Er, this flag was used as the gag on the victim. No prints or DNA on it.
These Crusaders aren't known to our friends at Thames House?
Agatha Jack tried to take English Flag into the mainstream.
Seems like a few splinter groups formed,
but no previous with the Crusaders.
Anything about the vic that appears significant?
Ali Hussein was the Muezzin. It's an important role in the community.
He leads the call to prayer,
responsible for keeping the mosque clean.
Most important, as Muezzin, it would have been his responsibility
to welcome any newcomer.
At 13:56, a white man with a black baseball cap walks into the mosque
carrying a blue bag.
It was Jummah - Friday prayers, lots of comings and goings,
larger congregations.
14:09, black baseball leaves the mosque empty-handed.
Head down. He's a pro. Knows where the cameras are.
We need to identify him.
Lana, I appreciate you coming in to make your report.
Anything about yesterday we need to know?
Er, the device appeared to be designed to stop us
gaining access to the room where the victim was located.
On closer examination, I discovered a secondary time switch
with a countdown and a tilt switch.
Um, unfortunately I ran out of time. Sonya, have you got the video file?
Yeah.
So, if you look at the impact, it's obvious they used a high explosive.
Like used on the compound at the bomb factory,
and found on the main charge at Westhaven.
But we need a chemical confirmation.
OK, that's a priority in tracking the bombers. Get on top of this.
Ma'am. Let's get moving.
All right, Wash? Stick the kettle on.
Could have used a second EXPO unit. Where were you? Just hanging out?
You're joking! Do I look like I'm joking? Where was my backup?
If you'd have done your job properly,
we wouldn't be in this fucking mess, would we?
Ten Liner request never mentioned a second team.
He's right. Never got any call for backup.
It's the Senior's role to request additional support, and that's you.
Why don't you get some sleep and sort your fucking head out?
Come on. Whoa-whoa-whoa.
Get off!
Lana!
VIBRATING
Billy, what?
Look at the bloody state of you.
A Halal butchers? Idiot!
You know, you are allowed to clean up, Billy.
Where's Becky?
She's at her mum's.
Here you are.
You need to get that hand checked out.
There could be glass and all sorts in there.
So, you like it here?
Yeah, it's a palace, innit?
Cracking views of Cally Road. Mmm.
You're not a vampire, Billy. You can open the curtains, you know.
Bloody hell, Lana.
See the mean machine's had a bit of attention.
Looks good.
Lana, keep 'em closed.
SHE SIGHS
Do us a favour, yeah? What?
Don't mention this to Mum and Dad.
Fine.
What are you doing, Billy? What have they ever done to you?
Killed Nut.
People like them.
We're at war, Lana.
War? You haven't got a clue!
What do you know about war? War against Halal butchers?
You don't know anything! It weren't them who killed Nut, you know.
Grow up, Billy.
We done? Yes, I am.
'Please get me out of here, please.
'Help me, please.'

Hey. Hey.
So, what's happening?
'The HMX-319 comes from Porton Down.'
But they couldn't tell me any more.
Wouldn't tell me any more.
'It's classified, Lana.'
What level of classification are we talking?
Well, beyond us bottom-feeders.
OK. OK, I'll speak to Hamilton or...
Thom? Yeah. Yeah.
'What are we dealing with here, Wash?'
What bombers have this kind of access?
I dunno, Sonya.
I'll give you a call in a bit, yeah? Talk later.
OK, bye. Bye.
SIGHS
SHE PANTS
WOMAN TO DOGS: Come on. Come on.
'This is Thom Youngblood, please leave a message.' Damn it!
Hello, mate. Eh up.
You all right?
Oh, you're gorgeous.
Meet Nelson. Nelson, Wash.
Is he yours? No, no, he's Elly's.
Er, sorry, I'm a bit... That's all right.
I'm just nipping out for a bit. OK. All right.
How you doing? Yeah, good, good.
You find it all right? Yeah, fine.
It's good, innit? Vietnamese weasel coffee.
What?!
Trust me, you don't wanna know why it's called that.
Right, so you're a coffee expert? Sure.
Though lime and soda's more of my specialist subject.
Oh, wish I was on them the other night.
Yeah, you were a mess.
I know. I mean, like, totally gone.
Wow. All right, shut up!
If you can't cut loose at moments like that, when can you?
Well, you didn't. Hmm.
I've got too much up here. I just can't.
Demons waiting to come out and play, you know?
You know, I've still got an evac pack next to my bed
just in case they call me out.
It's tragic, I know.
No, I get it. I feel the same.
It's... It's hard to talk about, innit?
I feel like if I told my mates, they'd think I was losing it.
Hmm.
We lose part of ourselves out there. We never get it back.
Hey, you know what we need, right? Come here.
What? What?!
Buckle up.
Where are we going? Keep cool.
Oh, my God, my coffee! Here.
I don't understand where we are!
Might wanna put your bag on the other shoulder. What is this, mate?
Just trust me.
Eh up, Maz.
Hiya, Karl.
Welcome to paradise.
Drink? Yeah.
Oh, bollocks.
I set you up. Thank you very much.
Shot.
Oof!
Lot riding on this. Mate, I've neutralised an IED
while the Taliban are taking pot shots at my head,
so I think I'll be all right.
Oh! You sharked me, giving it the old, "I haven't played for ages."
Pretty good, Wash, I'll give you that.
No, keep your money.
Double or quits.
All right. Deal.
This time I won't mess about.
Oh, fighting talk.
You can rack up.
Show off!
Careful. Steady. Oh.
Oh, damn it.
So, does it get easier?
Yeah.
I-I mean... no.
Still hurts.
Still feel like I'm lost.
The army trained me, gave me a purpose, and now...
Yeah, I get it.
I had routine, I knew what I was doing.
When I stepped up to a device, summat took over.
My instincts kicked in.
Cos you've been trained to behave like that,
to be in a state of alertness, aggression.
You can't just switch that off when you get back.
When I joined 11 EOD, I thought I was the dog's bollocks.
You, cocky?
Never.
I nearly died on my first call out.
I'd missed a secondary that Terry had put in the hallway.
Stood back to admire my work.
Nut screamed at me to freeze.
I was inches away.
When you're looking at the big picture, you miss the detail.
Yeah, Nut used to say we've gotta be lucky
every time we step up to a device.
Bomber's only got to be lucky once.
And Nut's luck ran out.
Bollocks!
I froze at that mosque, Karl.
That happens.
I'm scared the next time I step up to a device
I'm not gonna know what I'm doing.
I'm scared I've lost my nerve.
I'm scared of taking up Nut's nine lives, scared I'm gonna lose my job.
Fear's what drives us on.
It's when you lose that fear that you need to worry.
You've just lost your mate. Give yourself a break.
Nut would have dealt with that device.
You don't know that.
Why beat yourself up over things you can't change?
Right, let me kick your ass at this fucking game.
Oof.
Mmm, good news.
Managed to get clearer CCTV pictures of the mosque bomber,
few streets away from the site.
We were able to identify him through our police records. Nic Roberts.
Record as long as your arm. Violent assault, armed robbery.
Member of English Flag till last year.
Any record of explosives training?
We're still digging.
Bastard.
Yeah, we've got an alert for him.
There's been sightings across London.
I mean, we're running down all known addresses.
Just a matter of time.
Great.
PHONE PINGS
Who's that?
Er, it's just Danny. Some stupid GIF.
Um, has, er, Hamilton been able to get in touch with Porton Down
about HMX-319?
We're on it.
You finished? Yeah.
PHONE PINGS
Is that Danny again?
Yeah.
Can I just-just for a minute? Sorry, just for a minute.
Um, it's been on my mind. We never had time to talk about the mosque.
His name was Ali.
He was married, he had two kids under three.
And I failed him. I failed his family.
But you know you didn't.
Firstly, you didn't, cos you didn't have a choice.
It was a complex device, Lana. There was literally nothing you could do.
You were up against all of it. I know. I know.
I know.
Cos if you weren't in the right place, or you weren't feeling OK,
you-you could feel like you could talk to me.
Yeah. Course I would.
Cos I love you.
And I just wanna protect you.
I've been thinking about it for a while.
Might be an idea for you to move in here with me, you know?
What?
Well, you like the place. Well...
It would be nice to spend more time together. Mmm.
Outside the office, away from work.
It's sorted, then.
DOOR OPENS
Oh! Sorry, Lana, I didn't realise you were here,
otherwise I would have got you one. You're OK,
don't worry about it.
All right, Wash? Yeah.
I'm sorry I went off on one. It was out of order.
No danger, Wash, we've all been there.
I shouldn't have had a go either. There's some nutter out there.
We need to be on our game. There's no point fighting amongst ourselves.
TV: 'Far-right group the Crusaders say they carried out the attack.
'Ayesha Campbell Khan, the former Shadow Defence Minister,
'is standing as the Labour parliamentary candidate
'leading a progressive alliance...'
So, you think it's some loon that's doing this?
What do they reckon in CT? They got a name or anything?
I don't know. Don't ask me.
Doesn't your fella tell you nothing?
What are you on about? Come on!
TV: '..worshippers in the Amburiq Mosque,
'but earlier, we caught up with her on a visit to the Westhaven Estate,
'devastated by the worst attack in this summer's bombing campaign.'
'We all feel the pain of this community.'
Oh, here we go.
Typical leftie, siding with the enemy.
Enemy?
We must bring these murderers to justice.
PHONE PINGS
TV: '..after candidate Agatha Jack...'
Danny, I'm off to BDC. See you in a bit.
All right, mate.
Oh, God.
So, that's our confirmation, then. HMX-319 compound.
Exact same levels that were used at Westhaven as well. Yeah.
We're dealing with the same bombers at Westhaven and the mosque.
The Crusaders are lying about the mosque being revenge.
It's been them all along. No response from Porton Down?
No, Thom... er, DI Youngblood hasn't even asked Hamilton for clearance.
Well, you need to tell Thom to get on it, then.
You know if I hadn't told you about me and Thom,
do you think you'd know? Is it that obvious?
No, not at all. Why?
It's just John said summat at work today.
I don't know how he'd know, unless he...
VIBRATING
Danny.
On my way.
The Crusaders have planted another device.
This is EXPO 2. What can you see?
'OK, so we've got a stationary black van outside an LGBT pub,
'the Five Oaks. Noticeable sag at the rear axle.'
Right, get everyone as far away from the van as possible.
We're nearly there. 'Yeah, received.'
Move, Danny, move. Copy.
SIREN BLARES
Can you just keep them moving down?
Further down! Take them beyond the cones!
Behind the cordon! Keep them moving!
Thank you.
Who's told them to come through that cordon?
Quick as you can, Danny, straight to there.
Truck arrived at 6:00pm.
Bar staff thought it was a beer delivery
till the driver did a runner.
At 6:25pm, the Crusaders sent us
an encrypted message claiming responsibility.
Is there anyone left inside? No.
Are you sure? Yeah.
Danny, eyeballs.
What have we got?
Er, we've got a big sag at the rear axle, that black van.
The pub's been evacuated
and everyone has been taken beyond the cordon.
It's well down on the back end. Yeah.
Must be enough explosive in there to take down the whole street.
HE SIGHS
All right, carefully open the door.
Must be a rental.
No-one keeps their motor that clean.
No wires.
All right, let's push on.
Come on out.
Get down!
Take cover.
We've got a shooter somewhere.
Shit.
Lana, robot's been hit. It's gone.
Fuck's sake!
See anything? Eyes on?
Nothing. No visual.
Sniper, top floor.
Central Eight Five, we have visual confirmation.
We have a sniper on the top floor flat opposite the Five Oaks pub.
Requesting additional firearms support team immediately.
Preparing to move! Move! Move!
SIRENS
This is Central Eight Five, requesting air support as well.
Randall, take Carney, head towards the target. Go.
Shit! 'ETA, three minutes.'
Central Eight Five, received. Air support incoming, three minutes.
Hey. The boot's fully loaded.
If it functions, it will total the whole street.
A single shot could trigger the device.
Well, we know where he is. What do we do now?
Danny, pigstick bag, now.
Robins, I need smoke grenades, now.
Get the smoke bombs out the back of the truck.
Come on, come on, come on.
SIREN
We good? Yeah.
Sam, we're gonna redeploy to the tower block.
Go. Green Team, on me.

Armed police! Armed police!
Danny! Yeah!
I've got the shot.
As soon as I hit the corner, take the shot.
Lana, you're in the danger zone.
Fuck!
Take the shot! That's an order!
Circuit's good.
Priming. Stand by.
Firing.
This is EXPO 2. Device neutralised. Repeat, device neutralised.

Just pull that down for me.
You got an ID?
Think it's our man.
Nic Roberts.
Yeah, I reckon so.
Danny, make this quick, yeah?
Yes, ma'am.
I'll speak to Sonya about forensics on the device. Yeah, OK.
It was good work back there with the smoke grenades.
Not exactly by the book, though. This is not Afghanistan, Lana.
Yeah, well, it was a volatile device. I had to move quick.
Thom.
Yeah, coming.
He wasn't responding to radio comms.
The gaffer send me up here to check on him,
and he was just lying there.
Carney, you need to report for forensic recovery.
Sir.
His missus is six months' pregnant.
Brown, um, go and write up your report. Both of you get some rest.
Yeah. We've all had a long day.
OK, lads. Let's go.
Believe me when I say this - we will catch these bastards.
Simon Randall was killed at the scene.
Here's where we are.
We now believe that there's a single bombing campaign
run by one group: The Crusaders.
We know at least one member of the cell - Nic Roberts,
the suspect we shot, Crusader number one.
But there's at least one other member, possibly more.
They've attacked a housing estate,
a mosque, and now the Five Oaks pub, an LGBT venue.
We know they're highly skilled with both explosives and weapons.
We know they're attacking public sites in London,
and we know they meant for us to trace their getaway van
to the supposed bomb factory.
But we don't know why, and we don't know why now.
Samira.
Andrew Phelan.
We now know he was Nic Roberts' cell mate in Ashcombe prison
for three months in 2015.
We brought him in for an interview.
What's this about? I've told you everything!
Do you know this man? Fuck! Nic!
Nic Roberts. What's that psycho gotta do with anything?
This is the man we think was behind the bombs at Amburiq Mosque,
the Five Oaks pub and Westhaven.
Westhaven?
Is there a reason you stopped sharing a cell with him?
Cos he attacked me, tried to stab me in the neck!
He's a paranoid psycho.
Thought I was grassing him up.
We think Nic Roberts had a personal grudge against Phelan,
which is why the Crusaders chose to use him as a patsy.
Sacrifice him as an excuse to kick off their campaign.
Nic Roberts ran at armed police in a suicide belt.
If the far-right are now using suicide tactics,
this is a worrying development.
What does the CCTV from the tower block tell us
about the second Crusader who killed Randall?
We have an extra police officer who's been unaccounted for
in our scene log. This is him leaving the building,
and then he slips out with the crowd, and from there
he gets into a white Prius, Romeo, X-ray, one, zero, X-ray, Mike, Golf.
We're still searching for the vehicle,
but obviously a Prius is a popular make.
We're looking for an Uber in a haystack.
As we saw at Amburiq, the attackers know where the CCTV cameras are.
Forensics detected no gunshot residue on Nic Roberts.
Crusader Two was our gunman. He knows how to move.
Knows how to behave like a firearms officer.
Potentially someone with training, then.
OK, let's focus on Crusader number two, who is still at large.
Get onto Thames House.
Crosscheck all military personnel, active and past,
with membership records of English Flag.
If that still leaves us with a broad range,
narrow it down specifically to personnel with firearms training.
Let's check on every single contact Nic Roberts has.
Anyone he knew inside, anyone else who was in the EF with him,
friends, other gang members.
This is a lot to organise for a two-man cell.
I want supply chains, hideouts. Get on your informers. Ask around.
Someone knows something. One last thing.
Nic Roberts didn't have bomb-making training,
so either attacker two does
or there's another member of the cell, the bomb-maker.
Let's locate him and find out.
Ma'am. Yes, ma'am. Yes, ma'am.
Hey.
Sonya, come and look at this.
Feel like summat's staring me in the face.
Any luck tracing the device from the brewery van? No, not yet.
These are from Vauxhall, right? Yeah.
Hang on.
Look at this from the first device at Westhaven,
the direction that the wires are twisted,
and the way the cables are cut.
It's the same technique. It's military training.
Everyone that did high-level training cuts their cables
and twists their wires like that. That's how I do it.
They know how to bypass our ECM,
they know where to put the secondaries,
they know call-out times, how we think, how we move - everything.
It's got to be an inside man.
Danny, Danny.
Bloody hell, have you got enough aftershave on?
Why, what's wrong?
Bit strong, no? Oh, please.
Didn't know you could even shave.
Wash, coming for a sarnie?
Senior buys. No, I've got paperwork.
Next time.
All right, see you later. See you in a bit.
