Naa'imur Rahman has been convicted over a plot to blow up Downing Street's gate and assassinate Theresa May

An ISIS fanatic has been found guilty of plotting to blow up the gates of Downing Street and assassinate Theresa May.

Naa'imur Rahman, from north London, wanted to set off a bomb in Downing Street before launching a 'full frontal assault' on Number 10 to try and kill the Prime Minister.

The plot was uncovered by the FBI and MI5 after an agent posed as an ISIS leader online in order to uncover Rahman's plans.

The 20-year-old had been in contact with his uncle, who had already travelled to Syria and joined ISIS, and they had exchanged bomb-making instructions, the court heard.

His uncle had told him to 'take a gun and go into Waitrose and shoot people,' Rahman told the Old Bailey.

When the uncle was killed in an air strike last June, Rahman went in search of ISIS contacts on Instagram but ended up contacting an undercover FBI officer who passed him on to MI5.

Rahman was motivated by the idea of being met by virgins in paradise after the attack, the court heard.

Police handed over this fake suicide vest inside a coat to Rahman in a bid to snare him. He was told by an undercover officer that the 'bomb' had a ten-metre spread and that pressing one button inside would be 'a wrap' - as he left the car he was monitored via drone by armed police

During discussions with an undercover officer known as 'Shaq', Rahman detailed his plan to blow up the gates of Downing Street and making a run for Number 10 - with the possibility of taking a hostage to get him inside an option.

He said: 'You know the gates of 10 Downing Street, so I want to get past the gate and if I can get to the door, like I want to try, inshallah [god willing], make a dash for Theresa May.

'I just need a backpack with stuff inside and a blade. I want to drop a bag at the gate so the gate blows up a bit and I can go through and then like make a run.

'I was thinking taking a human hostage until I get to the actual door, grab a human shield and then once I get close enough to the door, then I'll do what I can and then try and get inside.'

'You're trying to get into Number 10. That's your main objective?' 'Shaq' asked.

'Take her head off, yeah.' Rahman replied. 'I want to go to jannah [heaven] when I'm doing it,' he said.

'I don't want to come back. I want them to kill me, but I just want to do my thing before I'm killed.'

Officers made a fake pressure cooker bomb which they gave to him during the investigation

He said he was 'thinking a lot about hur al ayn [virgins of paradise] lol [laughs out loud]' adding: 'In sha allah [god willing] I meet them soon.'

The investigation was aided when he sent naked photographs of himself to an underage girl on Instagram and police got hold of his mobile phone.

Rahman later complained to the undercover officer: 'Wherever you walk in London is women with no haya [shame].'

After MI5 made contact with him online, Scotland Yard mocked up a pressure cooker bomb and a suicide jacket which they handed over to Rahman in a covert meeting in a car in Latimer Road, West London.

During the meeting with 'Shaq', Rahman was asked whether he had made his video swearing allegiance to ISIS, but he said he did not have time to record it.

'I was going to do a video and then your lot can post it on the dawla [ISIS] framework,' Rahman said. 'But yesterday I was really busy.'

The officer opened a holdall which contained a rucksack with a pressure-cooker bomb inside.

Family had sent money to ISIS fighter relative It can now be reported that two of Rahman's uncles were jailed two years ago after sending maternity pay from their sister-in-law's job as a teaching assistant to the third brother in Syria. The pair also sold their brother's BMW and his wife's wedding jewelry in order to raise £10,000 which they sent to the couple in Syria. The third brother, Musadikur Rohaman, had begged the authorities to return in order to get his baby son treatment on the NHS, before he was killed in June last year. Rohaman was said to have been involved in developing new weapons for ISIS and his nephew suggested he could launch an attack on the Wimbledon tennis tournament using a drone and even suggested launching attacks from a hot air balloon.

The court heard Rahman was told the bomb had a ten second delay to it and a 10 metre 'spread'.

'This one I put the last battery ... I press the button and I release it, it's a wrap,' Shaq said.

Adding: 'Basically when you press that, it detonates.'

As he walked from the vehicle, Rahman was filmed by a drone as he was arrested in the street by armed officers.

Rahman was known to the Channel de-radicalisation programme from October 2015 but by the time of the investigation had 'almost completely withdrawn', the court heard.

Prosecutor Mark Heywood QC said: 'His focus was attack planning in the UK. The evidence shows in detail his developing fervour as he at first assembled his plan, carried out reconnaissance and perfected his ideas and then acquired the means to execute it.

'At the last, he took back his own coat and his own rucksack, both modified with improvised explosives devices, so that he could achieve his settled aim of a full frontal assault on the gates and then the door of number 10.

'In this, he expected to die, but he also hoped for personal reward beyond death and, in doing so, to cause death and great fear in a place and to people symbolic of the country itself.'
