These are the pieces of a homemade bomb jurors were told almost blew up North Greenwich tube station.

Damon Smith was 19 when a court has been told he packed a rucksack with explosives and left it on the tube.

Had the device worked, it would have exploded just as people were being ordered off the Jubilee line platform at North Greenwich, jurors at The Old Bailey were told.

Smith, now aged 20 and of Abbeyfield Road in London, appeared at the Old Bailey yesterday, April 27, for the continuation of the trial.

Smith denies possession of an explosive substance with intent, contrary to the Explosive Substances Act 1883 but has admitted the lesser offence of perpetrating a bomb hoax.

The pieces of the alleged hand-crafted bomb included a £2 Tesco-bought clock and ball bearings the prosecution said were to be used as shrapnel.

Jurors were show CCTV footage which appeared to show Smith’s journey on the Tube on October 20 last year, starting at Southwark and getting off at London Bridge at 10.49am, where he left behind his rucksack.

The court heard bomb was set to explode 11 minutes later at 11.02am, and there were at least 10 passengers in the carriage at the time.

Passengers had reported the unattended bag and the driver took it, thinking it was lost property.

It was while he was en route to the next stop that he noticed wire poking out of a clock.

The court heard Smith had a keen interest in Islam, guns, explosives and gambling, and collected pictures of extremists, including the alleged mastermind of the 2015 Paris terror attacks.

After he was arrested, the court was told the autistic student admitted making the device but claimed he only meant it to spew harmless smoke as a prank.

Prosecutor Jonathan Rees QC told how Smith had printed off an al Qaida article entitled ‘Make A Bomb In The Kitchen Of Your Mom’ and made notes in green ink before shredding the sheets of paper.

He also allegedly searched the internet for an Islamic State magazine featuring an article about the bomb said to have brought down a Russian airliner in October 2015.

A shopping list for "pressure cooker bomb materials" was also allegedly found on an iPad ending in a note to "keep this a secret between me and Allah #InspireTheBelievers".

After he had planted the bomb, Smith went to his university campus at Holloway and searched for articles of the incident when he got home later.

The trial continues.
