Papua New Guinea's Prime Minister Peter O'Neill says police and the defence force are working to apprehend the man who claimed to have taken over the command of the Defence Force yesterday.
Colonel Yaura Sasa and up to 20 soldiers loyal to him are reportedly holed up at the Taurama Barracks, refusing to surrender until they are granted a pardon.
Yesterday, the group put Brigadier-General Francis Agwi under house arrest at Murray Barracks in the latest move linked to the power struggle between two political camps claiming to be PNG's government.
Colonel Sasa claimed to have been appointed Commander by Sir Michael Somare's regime.
Mr O'Neill says Colonel Sasa will have to answer to the law
"Our authorities are now working with Defence Force bring him in for questioning and they will deal with him in accordance with the rule of law and the appropriate heads of parliament. So we'll leave it to the authorities to their job."
