Police are no longer treating the death of a woman, found dead in a Melbourne hotel room Sunday morning after a buck's party, as suspicious.
The woman, aged in her 20s was found unconscious in serviced apartments on Sunday morning, rented by a group of men from interstate.
Four men all aged in their late 20s and early 30s and from the ACT and NSW were taken into custody before being released overnight.
It has been reported the men were part of a group in Melbourne for a buck's party.
The woman's identity is still unknown, but police say her death is not suspicious.
Investigators have been running forensic tests and an autopsy was done overnight to find out what happened to, and identify, the woman found in the Oaks on Market complex.
"Police are not treating the death of a woman located in Melbourne's CBD as suspicious," Victorian Police said in a statement today.
One of the men told The Age they had been "stitched up", but refused to comment on how they knew the dead woman.
Homicide detectives say she was wearing a black, long-sleeved top, blue denim shorts and white running shoes.
The circumstances surrounding the woman's death are being investigated and further reports are expected to assist with the cause of death.
The Homicide Squad are assisting local detectives with the investigation and a report will be prepared for the coroner, police confirmed.
