A teenager has been shot dead in broad daylight in south London, police said.

Officers said two men have been arrested on suspicion of murder after a young man was fatally shot in West Norwood.

Police and the London Ambulance Service raced to Friar Mews at about 4.10pm after receiving reports of a boy in his late teens “in a critical condition”.

Just over 40 minutes later the teen was pronounced dead, the force said.

The two males arrested are currently being held in south London police stations.

In a statement, the Metropolitan Police said: "Officers are in the process of informing his next of kin.

"Formal identification awaits; a post-mortem examination will be scheduled in due course. A crime scene remains in place.

"The Homicide and Major Crime Command have been informed and will be leading on this investigation.

"A number of enquiries including review of local CCTV footage and forensic analysis at the scene are in hand.

"Detectives are urging witnesses to speak to police at the scene, call officers, or Crimestoppers anonymously."

Mayor of London Sadiq Khan tweeted following the young man's death, saying: "This is a tragic, senseless act of violence - and the loved ones of this young man are in my thoughts."

A section 60 stop and search power was also authorised for all of Lambeth.

The shooting comes as another man was attacked in south London just minutes earlier. A man in his 30s was stabbed in the head in London Road, Sutton, at about 4.05pm.

His injuries were non life-threatening, police said, and a man was arrested on suspicion of attempted murder.

Any witnesses and those with information should call police on 101/CAD 5335 or Crimestoppers anonymously on 0800 555 111.
