Port Moresby police detained four suspects, who are now at the Waigani police station.
The woman was found early Saturday morning (Oct 28) in what the homicide describes as a very suspicious death.
The four suspects were rounded up and will now hand in their statements at the Waigani police station.
Homicide says after the suspects’ statements, the body of the woman will undergo a post mortem.
Meantime, the main suspect in the death of another woman, on the 25th of October, has been arrested and charged for wilful murder.
The suspect is the partner of the deceased, both from Wabag, in Enga Province.
The woman died immediately after sustaining a severe blow to the head during an alleged domestic issue.
The deceased had died on the spot at Manu Autoport on Wednesday morning, when the partner allegedly hit her on the head with an iron bar during a quarrel.
Homicide says for this case, the main suspect was aware of what he was doing but still went ahead, thus leading to his charge; he will be going for a hearing soon.
