A 16-year-old boy has been arrested on suspicion of murdering a convicted teenage drug dealer who was fatally shot in the head, Scotland Yard said.
Sharmaarke Hassan, 17, from Camden, north London, was shot as he sat on a bench overlooking Regent's Canal on Saturday night, according to local reports.
He died in hospital, becoming the 15th teenager to meet a violent end in the capital this year.
Earlier it emerged Hassan was found guilty of possessing cannabis and offering to supply the drug at Thames Youth Court last month.
The teenager arrested is in custody at a north London police station.
Hassan is believed to have been a member of a gang known as The Money Squad (TMS). The local authorities tried to ban alleged gang members from Camden at an Anti-Social Behaviour Order (Asbo) hearing a fortnight ago.
Orders were sought forbidding them from meeting more than five named individuals, but according to the Camden New Journal newspaper, a district judge refused interim orders on all but three.
Highbury Corner Magistrates Court confirmed Hassan was among those named on the Asbo application.
According to local reports, Hassan was shot as he sat with a group of youths on a bench in Gilbey's Yard, overlooking The Regent's Canal, on Saturday night.
A post mortem gave the cause of death as a gunshot wound to the head.
