Eleven people have been arrested over a teenager's murder in north-west London.
The victim, named locally as 17-year-old Marvin Henry, was found by police who were called at 0025 BST to a disturbance near the junction of Bray Road with Bittacy Hill in Mill Hill.
He suffered a fatal gunshot wound and is the second teenager to be shot dead in London in four days.
Officers are also investigating if the boy, who was known to them, died in a planned fight between rival gangs.
Ten males, who are aged between 14 and 18, are being questioned by police, along with a 21-year-old woman.
The boy's next-of-kin have been informed.
'Talked in lyrics'
Several people have left floral tributes at the scene in Bray Road.
More than 150m of road in the area has been cordoned off.
A 16-year-old boy, who knew the victim but did not want to be named, said: "He was a very popular boy, everyone knows him. He came from a big family.
"We would never expect any of these things to happen. It's not a bad area."
Another friend, a girl who would not be named, said: "He never stopped spitting lyrics [rapping], he always talked in lyrics, he never talked properly.
"It's just a shock that it's all happened here."
He is the 17th teenager to be murdered in London this year.
On Saturday 16-year-old Samuel Adelagun, of Newham, east London, was shot dead in Plaistow.
