A teenager has been shot and stabbed to death by an gang brandishing knives and a samurai sword in north London.

The older man's injuries are non life-threatening, the force added.
Detective Chief Inspector Katherine Goodwin, of the Met Police, said the armed attackers were riding bikes.
She said: "My team has established that the attackers were armed with at least one firearm, knives and a samurai sword. Some, or possibly all, were riding bikes.
"I know that people may be reluctant or afraid to speak with police, but making a single call could help to remove dangerous, violent individuals from your area and all information provided will be treated in the strictest confidence."
No arrests have been made. The incident took place in Vincent Road, a short distance from Wood Green station.
The road was closed and a police cordon was put in place while officers investigated. A damaged car was found at the scene, police said.
