She was found in a serviced apartment at Oaks on Market in Melbourne's CBD, where a group of men from Canberra were celebrating a buck's night.
Four men are in police custody after a woman's body was discovered inside serviced apartments in central Melbourne.
It's been reported that one of the men initially thought the tragic find had been part of "one big stitch-up... but it turns out it wasn't" according to the Herald Sun.
Police were called to investigate around 8am when the body was found on the 10th floor of the Oaks on Market building that was being rented out by 11 men.
The responding paramedics later pronounced her dead.
"The exact circumstances surrounding her death are still to be established", Victoria police said. Those who were taken into custody to assist homicide squad detectives with inquiries and were later released.
Four men, all aged in their late 20s to early 30s from the ACT and NSW, are now in custody assisting with the investigation.
She was dressed in blue denim shorts, a long sleeve black top and white trainers.
