BANGKOK (AP) — Police on the scenic resort island of Koh Tao in southern Thailand conducted a sweep of hotels and workers' residences Tuesday searching for clues into the slayings of two British tourists whose nearly naked, battered bodies were found on a beach a day earlier. More than 70 police officers were deployed to Koh Tao, a popular diving destination in the Gulf of Thailand, as the country's leaders called for a swift investigation into a pair of brutal killings that marked a new blow to Thailand's tourism industry. The pair traveled to Koh Tao with friends and met each other on the island while staying in neighboring rooms at Ocean View Bungalows, said police Maj.
