East End actor Adam Deacon has been found guilty of harassing his former mentor – Kidulthood writer Noel Clarke.

The 32-year-old from Bethnal Green sent hundreds of abusive messages and incited people to hurt Mr Clarke after the two fell out following a disagreement over a film’s title.

The court was told that during the period of harassment Deacon encouraged a fan to post an image of Mr Clarke's children on Facebook 81 times in one day.

Deacon broke into the acting world as troubled teen Jay in Kidulthood, where he met Mr Clarke, who wrote the cult flick. However the pair fell out during Deacon’s directing debut with Anuvahood.

Mr Clarke told the court Deacon claimed he had been bullying him “for as long as he could remember” and he was responsible for Deacon not getting an agent in the business. Mr Clarke denied any of this was true.

Deacon reportedly showed no reaction as he was convicted at Hammersmith Magistrates’ Court on Monday, July 20.

He will be sentenced on Thursday, August 20.
