A man found dead in a Thames laneway was a 36-year-old local, police say.
The man's death is still unexplained, but police say his fatal injuries have raised concerns and prompted specialist staff to join the investigation.
The body was found in a service lane between Queen St and Mary St at around 7am on Monday.
Although police say they've identified him, his name will not be officially released until his next-of-kin are notified.
Police are urging anyone who saw anything suspicious in service lane six, or in the central Thames area between 4pm Sunday and 7am Monday to contact them.
