A second teenager has been stabbed to death in less than 72 hours in Newham, east London.
The 18-year-old was attacked in broad daylight in Coolfin Road, Canning Town on Monday.
Police officers and London Ambulance Service attended at 2.45pm but despite their best efforts, he was pronounced dead at the scene.
A crime scene remains in place and enquiries into the circumstances continue.
Scotland Yard said there had been no arrests.
Police have been granted extra stop-and-search powers under section 60 for the whole of Newham between 4pm on Monday and 7am on Tuesday.
So far this year, 13 teenagers have been killed in the capital. Last year, 15 teenagers were killed.
Fares Maatou, 14, was killed outside a pizza restaurant less than two miles away in Barking Road, Newham on Friday during a weekend of bloodshed.
Another 14-year-old boy appeared at Stratford youth court today accused of murdering Fares, who was in his school uniform when he was attacked.
The accused teenager, from Grays, Essex, spoke in person to confirm his name, age and address.
The court heard that Fares died after suffering stab injuries to his upper body.
It was alleged that a “knife cane” – a type of modified walking stick hiding a blade – was used to carry out the attack, which took place after a fight broke out.
Fares had been riding on an electric scooter before the incident took place, the court also heard.
A 15-year-old boy arrested on suspicion of murder on Saturday remains in police custody.
Two other 15-year-old boys held in connection with the incident have been bailed to a date in late May.
A total of 34 murder investigations have been opened in London this year.
Forty minutes after the teenager’s killing this afternoon, a 17-year-old boy was knifed in East India Dock Road in Polar, near the junction with Hale Street.
Fifteen minutes later, an 18-year-old boy was found with a stab wound to his leg in Quarles Park Road, Romford.
Both teenagers were taken to hospital for treatment and expected to make a recovery.
In a separate incident, two girls were stabbed in West Norwood yesterday afternoon.
One aged 16 is in a serious but stable condition with life changing injuries. The other girl, 17, is recovering from the attack.
Just hours after Fares’s killing, a 22-year-old man was stabbed in Bermondsey. His condition was described by police as life threatening.
