A 16-year-old boy who was stabbed to death in north-west London was being chased by three men with machetes, according to a witness.
The witness, who did not want to be named, said the young men were “screaming and laughing” as they pursued the teenager through Camden late on August 12.
She said the victim could be heard banging on a family’s front door in a desperate appeal for help before he was stabbed and the attackers fled in a car.
“I was just in my room and all I heard was screaming and shouting. Through my bedroom window I could see everything,” she said.
“We just saw the three boys holding him. He said 'help me, help me, help me'. He collapsed on the floor and then it was quiet.”
Police said the boy was pronounced dead at the scene and a murder investigation has been launched.
Detective Chief Inspector Paul Healy said the attackers’ vehicle was discovered burnt out nearby.
“Another vehicle believed to be involved in the incident was also found burnt out some distance away,” he said.
A man who lives near Camden’s Munster Square estate and wished to remain anonymous said it had recently become a hotspot for drug taking and gangs of men regularly gathered there.
Anyone with information is asked to call police on 101 and quote incident number CAD8433/12Aug.
