Police have launched a murder probe after a teenager was shot and killed in east London.

A 19-year-old man died in hospital after being rushed there by friends after he was shot in the incident in Walthamstow at around 11pm last night, police said.

Officers were called to reports of a shooting on Vallentin Road.

The victim's friends reportedly tried to save the man's life but he was later pronounced dead at 11.38pm.

Two other people, a 17-year-old boy and a 24-year-old man, were also seriously injured in the shooting, although their injuries were not life-threatening.

A resident who lives in a flat overlooking the street said he woke up to find police cars and uniformed officers had taped off both ends of Vallentin Road.

The resident, who asked not to be named, said: "It is just sad.

"A shooting is horrible. I feel saddened for the family but I guess this sort of thing can happen anywhere now these days."

He said he woke up to find police cars parked either end of the road with uninformed officers at a police cordon.

The fatal shooting comes less than 24 hours after a 20-year-old man was killed in a "senseless" stabbing at a house party in north-east London.

The victim, 20, named online by his DJ name Nana Banger, died after being stabbed at an 18th birthday party in Stamford Hill.

There have been more than 100 homicides in the capital so far this year.

Detectives are appealing for information over the shooting on Saturday night.

A spokesman said: "The victim - a 19-year-old man - was driven by friends to a north-east London hospital, where he was pronounced dead at 11.38pm.

"Officers believe they know his identity, but await formal identification and confirmation that next of kin have been informed.

"A post-mortem examination will be arranged in due course."

No arrests have been made.

Witnesses are being urged to contact police on 101 or Crimestoppers on 0800 555 111.
