The identity of a man whose body was pulled from the water opposite St Kilda Marina remains a mystery more than 24 hours after he was found.
The man's body was pulled from the water by several people, before police arrived at about 1.20pm on Sunday.
The grim discovery occurred during the St Kilda Festival as an estimated 460,000 people flocked to the area for the annual event.
The man's death is not being treated as suspicious, but police have made a public appeal for information in a bid to identify him.
He is described as being aged in his 30s, with an olive complexion, thin build, black hair, a short dark beard and a distinctive tooth behind his two front teeth.
He was found wearing black pants and a vest with no shoes.
Police have confirmed the man's death was not linked to the nearby festival on Sunday.
A computer-generated image, along with a photo of his mouth, has been released in the hope that he may be identified.
