A 16-year-old boy is in a critical condition in hospital after he and another teenager were stabbed by knifemen on mopeds.
The 16-year-old boy, who has not been named, is being treated for stab injuries to his torso which police believe were sustained after he was attacked by a passenger riding on the back of a moped.
A second boy, aged 17, was also treated for stab injuries following the attack in London, but has since been discharged from hospital.
Police today launched an appeal for witnesses and information about the attack.
A spokesman for the Met said: “At this early stage detectives believe that the victims sustained their injuries after two mopeds each with a rider and pillion passenger approached them.
“The pillion passengers then attacked the victims before fleeing on the waiting mopeds, heading in the direction of Mount Nod Road. Neither of the pillion passengers is believed to have worn a helmet.”
There have been no arrests.
