Boy, 16, Critical After Moped Stabbing Attack

Both boys were taken to hospital with stab wounds to their torsos after the attack, which happened in Mountearl Gardens in Streatham, south London.

The second victim, 17, was treated for his injuries and later discharged.

Police believe the boys were approached by two mopeds, each with a rider and passenger on board.

"The pillion passengers then attacked the victims before fleeing on the waiting mopeds, heading in the direction of Mount Nod Road," Scotland Yard said.

"Neither of the pillion passengers is believed to have worn a helmet."

Both police and the London Ambulance Service were called at around 5.30pm on Wednesday, 30 December following the attack.

:: Officers are appealing for witnesses or anyone with information to come forward and contact Lambeth CID on 101.
