Papua New Guinea's Chief Ombudsman has confirmed receiving a complaint from activist Noel Anjo on his alleged kidnap by supporters sidelined Prime Minister Sir Michael Somare in February last year.
The Chief Ombudsman Chronox Manek said his office is looking into the allegation as all documents have been furnished.
Mr Anjo alleges he was kidnapped and taken to the residence of the Prime Minister where Sir Michael, his wife Lady Veronica and other members of their family beat him up.
An outspoken critic of Sir Michael, Mr Anjo says police failed to properly respond to his complaints about the incident.
"The prime Minister's plan was to kidnap me in order to take my life or just murder me. Somehow I was lucky enough to be saved. They [police] unlawfully imprisoned me, saying I was tracking the Prime Minister... I never even threatened the Prime Minister. I'm not a criminal. I'm not representing any terrorist organisation to the country."
Sir Michael Somare says the events outlined by Mr Anjo never happened.
