Papua New Guinea's Chief Justice Sir Salamo Injia has been taken in by police for questioning.
The police spokesman Superintendent Dominic Kakas says Sir Salamo is being interviewed by police investigators at police headquarters in Port Moresby.
He says he is waiting for details and will issue a statement shortly.
The government of Peter O'Neill in early February suspended the chief justice pending an investigation into alleged mishandling of court funds.
Sir Salamo also presided over last year's leadership Supreme Court case and found Mr O'Neill was unconstitutionally elevated to the prime minister's office over long time incumbent Sir Michael Somare.
