An undercover police officer has denied putting an alleged rapping jihadi “on the spot” about getting a gun when they met in south east London. 

The officer, known as Rachid, spent nearly four hours chatting with Sahayb Abu when they met in Surrey Quays on June 30 last year.

Abu, 27, had suggested getting together after Rachid told him in Telegram chat that he had access to firearms in North Africa, the Old Bailey heard.

In a transcript of their conversation, Abu returned to the subject, saying: “You were talking about this… You can get silah (guns) in here.”

Rachid said yes and asked if he was “sincere”.

He said: “You’re my brother, man…

“Please don’t take it the wrong way what I’m about to tell you… but we’re talking about our security.”

Abu agreed: “Yeah, security, yeah.”

The officer told him: “If you want it then you come to me and say ‘Akhi (brother), you know that duty free (gun) we’re talking about, I want it inshallah (God willing)’ and then I’ll sort it for you.”

He told Abu that if he was “sincere” and wanted it then he would help.

But he added: “What I don’t want, and I’m not saying you are like that, don’t wanna talk, just talk for the sake of it.”

Jurors were told that “silah”, an Arabic word, and “duty free” were both code words for guns.

Abu said he knew what Rachid was saying.

He told him: “So even for someone like me there’s no point in my taking it… and then keeping it in my house for three years.”

Cross-examining the officer, Michael Ivers QC asked: “Are you putting him on the spot? Put up or shut up?

“Do you accept that you were putting him on the spot in terms of do you want one or not?”

Rachid, who gave evidence from behind a screen, replied. “No.”

Abu also told Rachid about his brothers, Wail and Sulaiman, who are believed to have been killed in Syria.

The officer told jurors that he recognised the pair after Abu sent him a photograph of them.

The court has previously heard that the unemployed defendant bought an 18in sword, a knife, balaclava, gloves, hat and combat body armour before his arrest on July 9 last year.

Sahayb Abu exchanged raps with his brother, Muhamed Abu, 32.

One referred to Fusilier Lee Rigby, the British Army officer who was murdered near the Royal Artillery Barracks in Woolwich, south-east London, in May 2013.

Sahayb Abu rapped: “I’m trying to see many Lee Rigby’s heads rolling on the ground.

“Man I shoot up a crowd cos I’m a night stalker, got my shank got my guns straight Isis supporter…”

He also posed in the hat and balaclava he had bought online in home-made videos which were shown in court.

In one of the short clips, Sahayb looked at the camera and said: “What, are you talking to me? … Boom!”

In another, he put on the balaclava and said: “Guess who? Uh huh yeah.”

In a third video, he rapped, wearing a hat and face covering, about “militant born, militant wear” and “militant camo” (camouflage).

He concluded by saying he was “just waiting on the body armour…. the body armour stop a bullet”.

He then gestured with his hands, imitating firing a gun, and exclaimed: “Boom.”

Sahayb Abu, of Dagenham, east London, denies preparation of terrorist acts.

Muhamed Abu, of South Norwood, south-east London, denies failing to disclose information about acts of terrorism.
