A teenager who died after he was shot in the chest has been named by police.
Mohammed Hussein, 19, was found collapsed in Bounces Road in Edmonton, north London, at around 9.45pm on Monday.
Neighbours ran to help and paramedics battled for half an hour to save him but he was pronounced dead at the scene.
Jordan Simbananiye, 18, said: "At first I thought it was a firework, but then, when I looked out of the window and saw all the police and paramedics, I realised someone had been shot. They spent about 20 or 30 minutes trying to resuscitate him but then after about half an hour they put a blanket over him.
Another witness, Alexandra Koohi, said she heard shouting and then around an hour later shots were fired.
She said: "I heard lots of shouting outside the kebab shop, then an hour later I was in my bedroom and I heard two shots. I looked out of my window and the guy was lying on the floor and there was blood everywhere."
She said he had been shot twice in the chest and that she and a neighbour ran to try to help him. The 21-year-old, who is Hungarian, said: "It's a shocking incident, it's scary to think this kind of thing can happen in your neighbourhood."
She saw three men running away after the shooting.
A third resident, who did not want to be named, said: "Earlier in the night a group of guys chased after the victim, who was in a car with a mate, and smashed a window. He then came back later and that's when the shooting happened. He was with three of his friends and I think they ran off when he was shot."
Detective Chief Inspector John Sandlin said: "I am appealing for anyone who was in the vicinity of Bounces Road or Walbrook House at 9.45pm to help us with our investigation. Likewise, if you have any information - no matter how small - that can help identify those responsible, please come forward and assist us."
