Damon Smith, 20, had a keen interest in weapons and pics of ISIS fighters in his computer, a jury was told

AN Isis Inspired Teenager who is accused of leaving a bomb on a Tube train had been obsessed with explosives since he was 10, a court heard today.

Damon Smith, 20, had also stood in front of a TV to take a picture of himself with one of the Paris terror attacks terrorists killed in a police raid in November 2015.

The teenager, who has Asperger's Syndrome, left the homemade device on a Jubilee Line train at North Greenwich Tube station on October 20 as he headed to his morning lecture.

The Old Bailey heard that when arrested, police discovered Smith was obsessed with weapons and had pictures of ISIS fighters on his computer.

Smith told a forensic psychiatrist that he had always been fascinated by weapons and that he had only planted the device for a prank.
