A 14-year-old boy has been stabbed to death by attackers who knocked him off his moped, the Met said.

The wounded teenager was found in Bickley Road, Waltham Forest, at 18:30 GMT on Monday.

Detectives believe his moped had been involved in a crash with a car, after which three men got out the vehicle, stabbed the victim and drove off.

He died at the scene and his next of kin have been informed. No-one has been arrested.

A cordon is in place and inquiries continue, the force said.

"It has now been established by detectives the boy was riding a moped that had been involved in a collision with a car," a statement added.

"It is believed that three males got out of the car and then stabbed the victim before returning to the vehicle and driving off."

Residents who live on Bickley Road told the Press Association they had not heard any shouting or screaming.

They said it was not until they saw the blue flashing lights from the emergency services that they knew something had happened.
