POLICE say a British man and his Thai wife have been robbed and beaten to death at a seaside resort south of Bangkok. Police Major General Wichean Tantawiriya says three Thai men - a security guard and chef at the resort and their friend - were arrested today and had confessed to killing the couple and taking a mobile phone and 5000 baht ($155). Wichean says the bodies of Michael Raymond, 68, and Suchada Bowkamdee, 52, were discovered yesterday in their bungalow at the Jack Beach Resort in Prachuap Khiri Khan province, 350km south of Bangkok. He says they had checked in a day earlier. Wichean says two of the three suspects were addicted to methamphetamine, a stimulant, and needed money to buy drugs.
