Tourist found dead after island rave party

"An investigation suggests she might have been raped and killed," Maj Pissanu Bia-kaew, a Tourist Police inspector, said.

The tourist, in her late 30's and known only as Anstris, was found dead on a beach stripped from the waist up and showing clear bruises on her neck.

Police believe she came to the island to enjoy the party on Saturday night, which attracted about 10,000 revellers.

Colonel Charoon U-chuparp, superintendent of Ko Pha-ngan Police Station, said local and tourist police were now trying to find the murderer. "We will bring the culprit to justice," he said.

Charoon also expressed concern that the case would hurt Ko Pha-ngan's image and tourism industry.
