A Swiss woman, aged 57, has been found dead among rocks at a waterfall in Phuket on Thursday afternoon. She was believed to be raped and murdered.  Police were informed after her body was found at about 1.30pm.

The body of a woman, about 164 centimetres tall, was found face down in the water among rocks about one kilometre from the entrance of the Ao Yon waterfall in tambon Wichit.

She was wearing a pink T-shirt, a jacket and a necklace with a silver-like coin. Police estimated she had died at least three days ago. They also found what appeared to be her passport and name card.  A source from the Immigration Bureau said the woman was identified as Nicole Sauvain-Weisskopf.

Near the body, police spotted jean shorts and black Nike trainers and a mobile phone.

An immigration police source said the woman had arrived alone from Singapore and stayed at Dusit Thani Laguna Hotel from July 13 to 27 before moving to The Mooring Resort Hotel. A witness saw her walking out of the hotel towards a beach at about 2pm on Tuesday.

The body was sent to Vachira Phuket Hospital for an autopsy. Police were gathering evidence and investigating the death.
