Woman and three men arrested over fatal stabbing in London

A woman and three men have been arrested over the murder of a man who was stabbed to death in northeast London on Wednesday.

The victim, who is thought to be in his 30s, was found with knife wounds in Matthias Road, Stoke Newington, early on Wednesday evening.

An air ambulance and London Ambulance Service medics attended after the man was given CPR by police, but he died at the scene.

Police believe he was attacked on nearby Cowper Road and crime scenes remain in place at both locations.

A 33-year-old woman and three men, aged 57, 58 and 62 were arrested on Thursday on suspicion of murder, police said.

They are being held at a London police station.

Detective Chief Inspector Paul Considine said: "This attack took place in the early evening, in a residential street and in broad daylight.

"There would have been people around and I need those people to call police.

"Whatever you saw, whether the fatal assault, the events leading up to it or the aftermath, it is vitally important that you call us.

"It is only by people working with police that we can make London safe and your call may be vital in helping us understand how a young man came to be brutally killed."

Police believe they know the identity of the victim and his next of kin have been informed, but formal identification has not yet taken place.
