An “extremely devious” Sunbury teenager has been jailed for at least 34 years for planting a bomb on the Parsons Green Tube, injuring 51 people.

The Old Bailey heard 18-year-old Ahmed Hassan wanted to avenge the death of his father in Iraq and was “disappointed” when the bomb only partly detonated in a huge fireball last September 15.

The jury rejected his explanation that he only wanted to act out a fantasy like the Tom Cruise film Mission: Impossible and convicted him of multiple attempted murder on March 15.

Twenty three people were hurt in the explosion, suffering serious burn injuries, and a further 28 were injured in the resulting stampede.

Victim statements were read out in court detailing the nightmares endured since the attack.

Commuter Stephen Nash said he had to give up his job as a social worker due to his fear of getting on the Tube.

He was left shaking, unable to sleep and anxious after the attack, in which he suffered severe burns to his head and ears as well as blisters to his mouth and nose, and now avoids travelling in to the capital.

In a victim impact statement read by Prosecutor Alison Morgan, Mr Nash said: “Since the attack I have not used the Tube.

“I believed I was going to die so, due to fear, I don't use the Tube.

“I don't go into London any more.

“I don't like being amongst crowds.”

Another victim, Lucinda Glazebrook, suffered superficial burns to her face and hands, and has been diagnosed with post-traumatic stress disorder.

In her statement, also read by Ms Morgan, she said: “I view myself as a changed person.

“I believed I was going to die.”

Ann Stuart said she had been left “on edge” and “tearful for no discernible reason”.

She said she has terrible nightmares.

Daniel Prieto, who suffered burns to his neck and had his eyelashes singed in the blast, said he cannot bring himself to use Parsons Green station because it “brings back bad memories”.

He added that his life had “changed completely” and said he had to receive treatment from a psychologist “to overcome the effects of the explosion”.

Hassan made the bomb with 400g of “Mother of Satan” explosives and 2.2kg of shrapnel while his unsuspecting foster parents from Sunbury were on holiday in Blackpool.

The judge said Hassan was a “dangerous and devious individual” who quietly went about plotting his attack with “ruthless determination and almost military efficiency while pretending to be a model asylum seeker”.

Mr Justice Haddon-Cave told Hassan: “Your intention that morning was to kill as many members of the British public as possible.

“I'm satisfied you were determined to create as much death and carnage that day as possible.”

He said had his bomb fully exploded, there would have been “numerous fatalities”.

He said Hassan had been shown “every kindness” since he arrived in Britain yet harboured “dark thoughts” and significant hatred and animosity towards the country that took him in.
