A man has been stabbed to death as he tried to intervene in a fight at an unlicensed music event in London.
Sean Williams, 34, died shortly after he was found with a stab wound to his neck on Thornsbeach Road, Catford, at about 05:30 BST on Sunday.
Another man, 37, also thought to have been at the event, attended hospital with a knife wound to his hand.
A 38-year-old man has been arrested on suspicion of murder and attempted murder, and remains in custody.
Det Ch Insp Kate Kieran said there had been “around 100 people at the event” in Culvery Road.
She said “a fight broke out between two men” and Mr Williams “intervened…and suffered a fatal injury”.
His next-of-kin have been informed, and a post-mortem examination is due to be held.
