THE JURY at the trial of the Parsons Green bomber have been shown photos inside his Surrey home where traces of explosive were discovered, alongside a bizarre video of him destroying a mobile phone.
Ahmed Hassan, 18, lived with foster parents in Sunbury, Surrey, at the time he left 400g of TATP on a Tube train, which partially exploded, the Old Bailey has heard.
When cops raided the property they found traces of explosive TATP on a container hidden in the wardrobe of the student's bedroom.
It was also discovered in a bag wedged behind the sofa in the conservatory.
Jurors also saw that the word bored had been repeatedly scrawled on the back of his bedroom door.
They were also shown a bizarre video Hassan created while a media student at Brooklands College in Weybridge, Surrey in which he destroys a Samsung Galaxy phone.
The video, shown to his class and to jurors, begins with pumping techno music.
Hassan, the cameraman, then soaks the handset in a series of liquids and powders before covering it in foil, baking it in an oven, then smashing it with a brick, a hammer, and a miniature statue of an angel.
He also attacks it with a drill and runs over it with a child's toy.
He then tosses the phone in a washer/dryer machine, before he covers the shattered device in a cloth and whacks it against a brick wall before tossing it in a toilet and flushing it.
The court heard how Ahmed's tutor was concerned by its contents.
The jury was also told how the teenage asylum seeker said it was his "duty to hate Britain".
Even though Hassan had been named student of the year in June 2017, his lecturer and mentor Katie Cable became concerned about his behaviour, the court heard.
Ms Cable even alerted the Prevent team after she saw a WhatsApp message on his phone saying: "IS has accepted your donation" in August 2016.
He also told her he blamed Britain for the death of his parents in Iraq and said: "It's my duty to hate Britain," the court heard.
The trial also heard from care home worker Zoe Spencer who told how she heard Hassan say that he had been a member of ISIS.
During an immigration interview she accompanied Hassan to he was asked: "Have you previously or are you any part of a terrorist group, for example, Isis?"
He replied: "Yes I was recruited by Isis for three months."
Jurors also heard how Hassan said he blamed the US after his taxi driver father was killed by a bomb in Iraq.
Asked about Hassan’s background Barnado’s worker Youseff Habibi told jurors: "His father was a taxi driver and one morning he went to work and a bomb fell on him and he died.
"And his mum died when he was much younger. He said 'I don't remember my mum'."
Prosecutor Alison Morgan asked: "Did Mr Hassan ever say who he blamed for that?"
Habibi replied: "America. He said it was American soldiers and American army bombing.”
He also told how he caught Hassan listening to an Arabic song on YouTube along the lines of "coming to the slaughter in your own home" when he was living in a children's home in Surrey.
Hassan, now 18, allegedly packed a bucket with TATP explosives and shrapnel and left it on the District Line train on September 15 last year.
It partially exploded causing a fireball to rip through a carriage during the morning rush hour, the Old Bailey has heard.
When Hassan was picked up by police at the port of Dover the next day, he admitted he had made the bomb.
Hassan has denied attempted murder and using the chemical compound TATP to cause an explosion that was likely to endanger life.
