Papua New Guinea's police commissioner, Anthony Wagambie, says the acting prime minister's son, Theo Abal, will be charged with murdering a woman whose body was found at the prime minister's residence on Monday morning.
In a statement, Mr Wagambie, has dismissed any fear of interference from the acting prime minister, Sam Abal, saying the police will do their duty without fear or favour.
He says Mr Abal has been very co-operative with police so far.
Mr Wagambie says they've completed their interviews and are now waiting for a positive identification of the dead woman before charging Theo Abal.
He says they have an unconfirmed report that she was a 29-year old from Kaita Village in Gulf Province, working as a waitress in Port Moresby.
