A gun-obsessed jihadi who claimed to be on the MI5 payroll has been jailed for four and a half years for having a stash of terror training videos.
Muslim convert Mustafa Abdullah, 34, was stopped at Gatwick Airport last year as he returned from a trip to Syria.
Police examined his phone and computers and uncovered gun instruction videos and audio files on guerilla warfare and combat equipment.
The jury was also shown a photograph from April last year of Abdullah with an automatic rifle on his shoulder, recovered from his mobile.
The appliance engineer, of Binfield Road, Stockwell, south-west London, denied 14 counts of possessing terrorism documents or records and one of possessing a gun for a terrorism purposes.
He told jurors MI5 paid him £10,000 for helping them and insisted he only went to war-torn Syria to do humanitarian work.
However, the jury deliberated for more than 12 hours to find him guilty of 13 offences of possession of documents likely to be useful to a person preparing an act of terrorism. He was cleared of the remaining charges.
Jailing him, Judge Gerald Gordon said if he had not been arrested he had no doubt Abdullah would have returned to Syria.
