A 15-year-old boy has died almost a week after being stabbed in north London.

Perry Jordan Brammer was found at Willan Road in Tottenham shortly after 11am on Friday, having suffered multiple stab wounds.

The teenager, from Tottenham, died in hospital on Thursday, Metropolitan police said. A postmortem examination will take place next week.

Three men aged 20, 21 and 24, and a 17-year-old boy, were previously arrested on suspicion of attempted murder but were all released with no further action being taken, police said.

DCI Neil John, who is leading the investigation, appealed for information. He 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. 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.”

The death is the latest in a series of teenage murders in the capital. A 15-year-old boy was fatally stabbed in Byford Close, Stratford, on Tuesday evening after officers were called to reports of a fight.

Santino Angelo Dymiter, 18, from Plaistow, was stabbed to death in Chadd Green, east London on 26 August.

The week before, Amrou Greenidge, also 18, died in hospital after being deliberately knocked off his bike by a vehicle in Fulham and attacked as he lay on the ground on 18 August.

Solomon Small, 18, was knifed to death in Brixton on 15 August, while just three days earlier Alex Smith, 16, died after being repeatedly stabbed with a machete in Munster Square, Camden.

The murder in Tottenham is the 94th homicide in London this year. By the same date last year the homicide rate had reached 99, with the final total for 2018 reaching 128 according to PA – the highest total for a year this decade.
