Papua New Guinea police are set to lay a murder charge against the son of the acting prime minister, Sam Abal.
The police are questioning Teo Abal over the death of a woman on Mr Abal's property early on Monday morning.
The acting deputy police commissioner says the woman's aged between 20 and 30 and no one else is being sought in connection with her death.
Fred Yakasa says once the woman's identity's been established Teo Abal will be charged with wilful murder.
"This girl has been picked out from what information we're getting from a nightclub, from a lodge or a nightclub and so it's not a permanent relationship where someone would know about her identity. If the police had any idea about where about her parents or relatives you know then we have a suspect already."
Fred Yakasa says some people have already come forward and identified the woman by her first name.
