The lifeless and battered body of the woman was found at her family residence at East Boroko, Port Moresby.
The NCD metropolitan superintendent, Commander Perou N’Dranou, said according to reports received from Homicide, the body of the woman, from Central Province, was found under the house.
He said following observations from the homicide unit on ground at that time, the woman could have been beaten and raped in the early hours of the morning – between 2 and 3am.
However, it is still unclear on whether it was a gang rape or not.
The cause of death has not been established yet, but bruises on her body point to a possible death by strangulation or lack of air to her body, which could have been caused by blockage to her nose and mouth at the same time.
There are no possible suspects at this moment.
The body is in the Port Moresby General Hospital morgue and will go through an autopsy sometime this week.
