The Australian lawyer, Julian Moti is being questioned by immigration officials in Solomons Islands after flying into the country on a aircraft this morning from Papua New Guinea.
Officers from the Royal Solomon Islands police force are standing by to assist in the case if requested.
Mr Moti, who had recently been appointed Attorney General, arrived in the country without his Australian passport which was cancelled by the Australian government over alleged sex offences in the 1990s.
Our correspondent in Solomon Islands, Dorothy Wickham has the details.
"A chartered plane arrived in at Munda airport in the western province early this morning and disembarking on the plane was Julian Moti, and Robson, the Prime Minister Manasseh Sogavare's nephew who had been sent to Port Moresby as a liaison officer in this case."
Australian authorities have been seeking the extradition of Mr Moti.
