Another murder inquiry is underway in London after a man was stabbed to death.
The victim was found with multiple stab wounds near a tube station just before 10pm on Saturday night.
Police have sealed off a nearby park and roads near Turnpike Lane station in north London.
More than 70 murder inquiries have been launched in the capital since Christmas.
Scotland Yard believes the latest victim, who has not been named, was stabbed on Ducketts Common.
Witnesses near the busy Tube station watched in horror as medics performed CPR on the victim.
Matthew Smith tweeted: “Around 10 police vans at Turnpike Lane. Paramedics doing CPR on someone lying on the pavement. Horrible scenes.”
No arrests have been made.
A Met Police spokesman said: “Police were called at 9.47pm on Saturday to a seriously injured man in Green Lanes near to Turnpike Lane station.
“Officers and paramedics attended the location.
“A man, aged in his 30s, was found suffering stab injuries. He was pronounced dead at the scene.
“Officers believe they know the identity of the man and are in the process of informing next of kin.
“Formal identification and a post-mortem examination will be arranged in due course.”
Witnesses are urged to call police.
Since you are here
Since you are here, we wanted to ask for your help.
Journalism in Britain is under threat. The government is becoming increasingly authoritarian and our media is run by a handful of billionaires, most of whom reside overseas and all of them have strong political allegiances and financial motivations.
Our mission is to hold the powerful to account. It is vital that free media is allowed to exist to expose hypocrisy, corruption, wrongdoing and abuse of power. But we can't do it without you.
