The son of Islamist cleric Abu Hamza is to be sentenced for his part in an armed robbery at a jewellers.
Imran Mostafa, 20, of Deverills Way, Slough, who it emerged is the son of the controversial preacher, has denied robbery and possessing a firearm with intent to commit an offence along with 17-year-old Jonathon Abdul from London.
But the men were convicted at Norwich Crown Court after a trial in September.
They will be sentenced alongside Ossama Hamed, 19, of Greswell Street in Fulham, and Ahmed Ahmed, 20, of Nag's Head Road in Enfield, who previously admitted the same charges.
The raid happened at the Francis Wain store in King's Lynn on January 31. Gems worth about £75,000 were stolen in the smash and grab raid.
Judge Peter Jacobs had ordered that details of Mostafa's parentage should be the subject of a contempt of court order, meaning they could not be reported until the jury had reached a verdict.
Hamza last month pleaded not guilty to terror charges in a New York court following his extradition from the UK.
He denies charges that he conspired with US nationals to set up a terrorist training camp in the state of Oregon.
He will stand trial next August and will also face charges of abducting tourists in Yemen.
Another of Hamza's sons, Yasser Kamel, 20, was jailed for 12 months in 2010 after admitting violent disorder during anti-Israel riots in London.
