The son of controversial Muslim cleric Abu Hamza is one of two men to have been found guilty of carrying out a smash and grab raid at a Norfolk jewellers.

The raid at Francis Wain, in King’s Lynn, during which £83,000 worth of gems were stolen, happened shortly before 10am on January 31 and is said to have involved four men.

Imran Mostafa, 20, from Deverills Way, Slough, and Jonathon Abdul, 17, of Fulham High Street, London, had both pleaded not guilty to robbery and possessing a firearm with intent to commit an indictable offence.

But a jury at Norwich Crown Court has today found Mostafa, who it emerged is the son of Abu Hamza, and Abdul, who previously could not be named as he is 17, guilty of both counts.

They will both be sentenced at a date to be fixed alongside Ossama Hamed, 19, of Greswell Street in Fulham and Ahmed Ahmed, 20, of Nag’s Head Road in Enfield, who had previously admitted the same charges.
