Ten men including a sports agent have appeared in court accused of murdering an 18 year old man in a "revenge" attack over a stolen Blackberry.
Christopher Nathaniel, 40, his business partner Paul Boadi, 34, and eight others are accused of killing Danny O'Shea in Canning Town in December 2011.
The teenager died after being beaten with baseball bats and stabbed in the throat just yards from his mother's home, the Old Bailey heard.
Mark Heywood QC, prosecuting, said the defendants travelled to the area to "exact revenge" after Boadi's mobile phone was stolen a week earlier.
They all deny murder andconspiracy to commit grievous bodily harm.
