A teenager has been stabbed to death after a birthday party in London.

The 17-year-old was fatally stabbed in the street during a fight in front of party-goers in Granville Road, Brent, north-west London.

The teenager died at the scene of the incident, which took place around 11.30pm on Friday.

Another male, also believed to be 17, was taken to hospital, as was a woman in her early 20s, who suffered a hand injury.

No arrests have been made, and a murder investigation has been launched.

Detective Chief Inspector Mark Rogers of the Metropolitan Police said: “We believe that there was a fight following a birthday party, which would have been attended by a number of people.

“I would urge anyone who was there, and who has not yet spoken with officers, to please come forward. It is vital that we establish what happened.”

Chief Superintendent Dan Knowles, in charge of the North West Command Unit, said: “I know that the community will be shocked by this incident in which a young man has lost his life.

“We shall be working with our colleagues from Specialist Crime to ensure that this investigation proceeds as quickly and thoroughly as possible.”
