Three teenagers have been rushed to hospital after being shot in North Kensington.
The victims, aged 17, 18 and 19, were shot in the Mozart estate in west London at around 7pm last night.
Police hunting for the gunman are apparently investigating whether the incident was a botched drive-by shooting. The investigation is being led by detectives from the Met's Trident unit, which deals with gun crime in the black community.
No arrests have yet been made.
According to reports, the 17-year-old girl has already been discharged from hospital, while the other two victims are in a stable condition.
MP for Westminster North Karen Buck is understood to have visited the estate after the incident. She tweeted: "On Mozart Estate after reports of 3 girls being shot.
"Desperately worried about local gang and youth violence. We have to get a grip."
John Fearon Walk, the street on which the shooting took place, had been identified as a hotspot for antisocial behaviour in the past.
A spokesman for London Ambulance Service said: "Staff treated an 18-year-old woman at the scene. She was taken to hospital as a priority.
"Two other teenage girls, also with gunshot wounds, made their own way to hospital."
