In a refrigerator they found the carcasses of 23 squirrels - probably some of those chirpy characters who have disappeared from Phuket City hillsides recently - and a quantity of protected giant Asian river frogs, which are not native to Phuket.
The 14 frogs weighed in at 27 kilos.
The owner of the Mum Muang Lung restaurant, close to the intersection of Vichitsongkram Road and the Baan Kathu Baan Samkong Road, was asked by police to answer some questions.
Sumat Donya, 39, is likely to face more serious charges after police from Kathu Station in Patong went to the restaurant about 5pm last night in response to a tip-off.
Despite reports recently that the genitals of elephants were being taken by poachers in other parts of Thailand to sell to diners on Phuket, only squirrels and frogs were found after police raided the restaurant.
If you are what you eat, then Khun Sumat probably wishes he could hop away and climb a tree to hide.
