Police have launched a murder investigation after a man believed to have been in his 20s was stabbed.
Officers said they found the man with stab injuries in Kentish Town, north-west London, after being called at about 8.30pm on Monday.
He was pronounced dead at the scene near the Grafton Road junction with Vicars Road, despite the efforts of medics.
The killing came on the same day the prime minister hosted a summit on knife crime at Downing Street.
Theresa May said that the issue is “deep-seated” and will require a cross-society effort to tackle it.
However police officers, teachers and nurses criticised Government plans to make them accountable for failing to “spot warning signs” of violent crime among young people.
“We cannot simply arrest ourselves out of this problem,” May said.
The summit convened after days of violence across the country, including a slew of serious stabbings in Edmonton, north London, from Saturday night into Sunday morning, as well as the death of a 40-year-old motorist at the wheel of his vehicle in Clapham, south-west London, and a 29-year-old fatally stabbed on Thursday afternoon in Toxteth, Liverpool.
Hours later and police were responding to another fatal stabbing in the capital.
A friend of the Kentish Town victim told the Evening Standard: “He was loved. He has everyone out here, every culture in the area was out for him.
“He’s not lived his life yet.”
No arrests have been made in connection with the killing.
While formal identification is yet to take place, the man’s next-of-kin have been informed.
A post-mortem is due to be carried out.
