A 15-year-old boy has been taken to hospital after being stabbed in the latest in a spate of violent attacks.
Officers were called to Ripley Road in Canning Town at around 8pm on Saturday to reports of a stabbing, the Metropolitan Police said.
Emergency services attended the scene and the teenager was taken to hospital with stab wounds.
The force said that “officers await an assessment of his condition” and no arrests have been made.
It comes after another teenager, who was stabbed to death in Brighton Road in Croydon, south London, at 9.10pm on Thursday was named as Kye Manning.
Mr Manning, 19, died at the scene at 9.50pm, Scotland Yard said.
A post-mortem examination has taken place and the cause of death was identified as a single stab wound to the heart.
A man has been charged with offences linked to the incident.
Mason Bird, 18, of Old Lodge Lane, Purley, has been charged with GBH, violent disorder and possession of an offensive weapon, police said.
Two men aged 18 and 20 remain in hospital, while a 17-year-old boy remains in custody. All three have been arrested on suspicion of murder.
A 15-year-old boy, also held on suspicion of murder, has been bailed until early August pending further inquiries.
