A man who died in a south London street “unintentionally” shot himself, police believe.
Officers responded to reports of “suspicious activity” in Sydenham Road in Sydenham at 15:45 BST on Sunday.
A 25-year-old man was found with gunshot wounds and pronounced dead at the scene.
Det Ch Insp Richard Leonard, of the Met Police, said officers believed “the man unintentionally discharged a firearm resulting in his fatal injury”.
The victim’s next of kin have been informed but he is yet to be formally identified.
One man has been arrested in connection with the investigation and remains in custody.
