A teenager has been knifed during a broad daylight attack in a busy north London high street.
Police and paramedics rushed to High Road, Wembley, around 3.30pm on Thursday to reports of a stabbing.
A 17-year-old was found suffering stab wounds and rushed to a central London hospital.
His condition is not yet known.
Witnesses described how the victim fled into a nearby cash and carry after being attacked by a gang of youths.
Ghanshyam Boricha, 26, who works nearby, told the Standard he saw a group of teenagers attack the youngster before he fled into a shop for help.
He said: “The guy who got stabbed was a teenager.
“He tried to run from there into Malar Cash and Carry and then the police arrived.”
Five people, believed to be in their teens, have been arrested on suspicion of affray.
They are currently being held at a north London police station, a Met Police spokesman said.
