A teenager is in a critical condition after being shot in the head.

The 18-year-old was attacked after a fight reportedly broke out at just before 3.30pm on Tuesday in Wightman Road, north London, near Turnpike Lane.

He was treated by paramedics and an air ambulance crew and is currently in hospital with life-threatening injuries.

One witness, a 24-year-old woman, told the Evening Standard: "I saw his friend crying and being comforted by police.

"The atmosphere was awful. People at the scene said there was a big fight for minutes before police arrived.

"There are normally people hanging around there but never normally in a threatening way."

Scotland Yard's Trident and Area Crime Command, that deals with gang crime and all non-fatal shootings, is investigating.
