Police in French Polynesia's Marquesas Islands are trying to find a German man who vanished during a hunting trip with his partner and a local guide on Nuku Hiva at the weekend.
Reports say the woman raised the alarm after she was allegedly raped by the guide who has been identified as Henri Haiti.
An additional 20 police have been sent to the area to try to find her partner Stefan Ramin who is 40 years old.
The German couple made the acquaintance of the guide after mooring their yacht in a bay.
They had been living on the yacht and according to their website planned to spend the next few months in French Polynesian waters.
