A man’s body was found in a Manchester city centre canal on Saturday and police are appealing for information from witnesses.
The corpse was found near to Canal Street – around Manchester’s popular Gay Village area – shortly before 1.50pm on June 9.
Emergency crews recovered the unidentified man and investigations are on going.
Detective Inspector Julian Flindle said: "We have launched an investigation into the circumstances surrounding this man's death, but we need accounts from any possible witnesses, and we also need to urgently establish this man's identity.
He added: "My message to all of those who are familiar to and use this part of Manchester city centre is that we have launched a thorough inquiry which aims to find out what happened.
"I understand there may have been some discussion and rumour about this incident, and all I ask is for people to come forward and tell us if they know anything that could help."
The man is described as white, of slim build, possibly in his late 20s to early 30s, about 5ft 8in tall and wearing a grey V-neck T-shirt with white buttons, black jeans and white Lonsdale trainers with a dark blue stripe.
