Investigations into the alleged rape of a local woman at the Manus Regional Processing Centre have been slow.
Three Australian men were accused of committing rape in mid-July after they were reportedly found naked with a local female employee sniffing an unidentified substance.
Provincial Police Commander Alex N’drasel says investigators are having difficulty in obtaining information because interviews with local staff from the centre have not produced enough information.
The woman in her 20s reportedly told police she was given pills and sexually assaulted.
He says two investigators from East New Britain have joined his team and he hopes a report will be furnished soon.
Police are investigating reports of "attempted rape, indecent exposure and sexual assault".
N’drasel says he has asked for the three Australians to be sent back to PNG and once a report is ready he will pursue that request with authorities.
Prime Minister Peter O’Neill told LOOP News he will be discussing this issue with Australia’s Tony Abbott during the Pacific island Forum Meeting next month.
