Damon Smith grins moments before police questioning of tube bomb

A weapons-obsessed student who became fascinated with terrorism has been found guilty of planting a homemade bomb on the London Underground.
Loner Damon Smith had been interested in bombs since the age of 10 and began researching how to build them using ISIS propaganda magazines found online.
The 20-year-old - described as still 'tied to his mother's apron strings' - even made an image of himself with Paris attacker Abdelhamid Abaaoud when the killer's picture was shown on TV following the 2015 atrocities in France.
Smith then began making his own device - using a Christmas tree light, sparklers and a thermos flash packed with ball bearings.
Smith left his device in an Adidas holdall on a Jubilee Line Tube train at North Greenwich Tube station - then headed off for his morning lecture.
The device failed to go off and the driver took it into his cab thinking it was lost property before carrying on with the journey.
It was only when he looked into the holdall that he realised it was a bomb which could go off at any time.
Smith was arrested after CCTV footage of him planting the bag from the train was linked to footage of him leaving the station.
The student, who was 19 at the time and suffers from Asperger's Syndrome, claimed the device had been a prank and that he had only planted it to cause delays and see if it would make the news.
The student said he just wanted to cause 'a bit of smoke' but had put the ball bearings in to make the device look authentic.
He denied possession of explosives with intent to endanger life and cause serious injury, but was convicted by a jury following a week-long trial at the Old Bailey after less than an hour's deliberations.
The would-be bomber looked stunned as the jury's verdict was read out but did not speak.
Smith, who grew up in Newton Abbot, Devon, did not give evidence at his trial but told a pyschiatrist he had been fascinated in bombs since childhood.
He had moved to London with his mother to study computer forensics at London Metropolitan University just a few weeks before planting the device.
Smith said he made his first replica pipe bomb aged 14 after reading the Anarchist's Cook Book online.
He is a judo black belt and an avid poker player and had won £500 from an online game on the morning he planted the bomb.
Dr Ian Cummings said in a report: 'He recalled watching the Boston Bombings and downloading the Al Qaeda magazine Inspire and visited some Islamic websites.
'He said at the time he didn't think it was an issue - he thought it was just an interest.'
Of the bomb plot, he said: 'He said he wanted to make a smoke bomb and had no expectation that it might cause harm - he admitted he had used ball bearings but more to give an authentic look than to cause harm.'
On the morning of 20 October last year Smith boarded a Jubilee Line train at Surrey Quays with the device in a bag and then changed at Southwark to go in the opposite direction.
He primed the timer mechanism on the device on the train by inserting batteries into the clock and then left the bag on the train between Southwark and London Bridge.
Two members of the public spotted it and alerted the driver at North Greenwich station.
But the driver thought it was lost property and took it with him into his cab - it was only on double checking that he noticed the wires protruding from the back of the clock.
Both the train and platform at North Greenwich were evacuated and the device was then made safe by a cutting wire.
Had the device detonated as planned, it would have gone off just as passengers were leaving the platform.
Later that night, Smith began making Google searches to try and find news of his bomb.
When he was arrested the following day on his university campus by armed officers, he was carrying a copy of the Quran in his bag along with his lecture notes.
At the south London address he shared with his mother police found bomb-making instructions and a shopping list of bomb components.
They also recovered a blank-firing pistol and a video of him firing the gun he had uploaded to YouTube.
He also had a carbon-dioxide powered revolver designed to fire ball bearings and a sheath knife which had also featured in YouTube videos.
An image of a handgun labelled '2016 Islamic State fighter' was found on his university computer, and he was found to have 'liked' various videos of explosions.
Smith had images of ISIS fighters and had searched for an issues of the terror organisation's online magazine Dabiq.
The issue he downloaded featured an article about the bomb which brought down a Russian airliner on 31 October 2015.
