The Parsons Green Tube bomber had the chemicals used in the explosive device delivered to a friend’s address in Thornton Heath, a court heard.
Iraqi asylum seeker Ahmed Hassan, 18, injured 30 commuters after detonating the device in a Lidl supermarket bag in the packed District Line carriage, the Old Bailey in London was told.
Hassan set up a new gmail account and bought the hydrogen peroxide at 10.51pm on August 26, using the name and address of his friend in Thornton Heath.
It was delivered to him on August 30, and the following day Hassan collected the substance from the Thornton Heath address.
“CCTV footage shows the defendant travelling back from Thornton Heath with a Lidl plastic bag containing what the prosecution alleges to be the hydrogen peroxide,” said prosecutor Alison Morgan.
Hassan loaded an explosive device with more than 4lbs of nails, screws and knives to cause ‘maximum carnage’ on a rush hour Tube train, the court heard.
Hassan, who arrived in the UK illegally on the back of a lorry in 2015, allegedly made the bomb using the explosive triacetate triperoxide (TATP) which was packed into a Tupperware container and glass vase inside the white bucket.
When interviewed by the Home Office when claiming asylum in the UK, he said he was fleeing ISIS – who he claimed kidnapped him, threatened to murder his family, made him train 1,000 soldiers to kill and give religious teachings.
The jury was told that some of the ingredients for the device were bought on Amazon and CCTV captured Hassan buying a drill in Aldi and batteries and a screwdriver set in Asda in Feltham.
Hassan allegedly used a £20 Amazon voucher he was given after winning a school prize at Brooklands College, when he became Student of the Year for his study of the Level 3 Diploma in media and creativity, to pay for the chemicals.
He then allegedly took advantage of his foster parents being on holiday to prepare 14oz of TATP explosives, using a friend’s address to take delivery of the largest ingredient.
His asylum claim was pending and he was living with foster parents Penelope Jones, 71, and her husband Ronald, 88, at the time of the attack.
Hassan, from Sunbury-on-Thames, Surrey denies attempted murder and using TATP (triperoxide triperoxide) to endanger life. The case continues.
