Tyler McDermott, 17, died Friday afternoon after a shooting on Thursday, and two men have now been arrested on suspicion of murder.
Police were called to Norman Road, Tottenham, at 4:20am to and McDermott was suffering from life-threatening injuries. He then died in hospital.
Detective Chief Inspector Neil John said: “These two arrests demonstrate the progress our investigation is making.
“However, there is still significant work to do to identify those involved in Tyler’s murder. There were a large number of people in the area at the time of Tyler’s murder and I am reiterating my appeal to anyone who was there, or who has information about this incident, to contact police immediately.”
Detective Chief Superintendent Caroline Haines, head of policing in Haringey, said: “My thoughts are with Tyler’s family following the tragic loss of another young life. You will continue to see an enhanced police presence in the area, and I would encourage local residents to speak with my officers if they have any concerns.”
