A 15-year-old boy has died after being stabbed in Haringey on Friday, 30 August.
Police were called at 11:14hrs to reports of a stabbing at Willan Road, N17.
Perry Jordan Brammer, from Tottenham, was found suffering multiple stab wounds and was taken by London Ambulance Service to an east London hospital.
Despite the work of the emergency services, he died on Thursday, 5 September.
His next of kin are aware and a post-mortem examination will take place next week.
Homicide detectives are investigating the murder and continue to seek information from the public.
Detective Chief Inspector Neil John, who is leading the investigation, said: “This attack happened in broad daylight and we believe there are people out there who know what happened.
“This was a sustained attack which has led to a boy aged just 15 losing his life.
“We are determined to find the individual responsible for this murder and we believe he fled the scene on a yellow bicycle which was later found abandoned nearby in an alleyway.
“We would urge anyone with dashcam footage which may show the attacker or the incident itself to come forward.”
