Detectives have arrested a teenager on suspicion of the murder of 14-year-old Jaden Moodie.
The suspect, 18, was arrested in Wembley, north west London, on Saturday morning, Scotland Yard said.
Jaden was stabbed to death on Tuesday January 8 after he was rammed off a moped by five men in a black Mercedes B class, police believe.
Three of the attackers got out and knifed Jaden before all of them fled in the car.
The suspect has been taken to a police station in central London where he is still being questioned, the Metropolitan Police said.
