Police launched a murder investigation after a man was stabbed to death in north London.

Officers said they found the man with stab injuries in Kentish Town, north-west London, after being called at about 8.30pm on Monday.

The man, in his twenties, was pronounced dead at the scene near the Grafton Road junction with Vicars Road, despite paramedics' attempts to save him. No arrests have been made.

Formal identification and a post-mortem examination are yet to take place, but the victim's next-of-kin have been informed.

It comes a day after police said they were hunting a knife-man who stabbed four strangers within a few hours over the weekend in the London suburb of Edmonton, less than 10 miles away.

Two men have been arrested but police have said the perpetrator, who stabbed his victims in the back, could still be on the streets. All four victims are in hospital.
