Cambodia authorities have issued a complaint to officials in Thailand over allegations that a Cambodian teenager was seriously injured by Thai policemen last month.

Uk Keorattanak, spokesman for the governor’s office in Banteay Meanchey province, said yesterday that a formal complaint was sent to the chief of the Cambodian-Thai Border Relations Office on Friday. It will then be passed to authorities in Thailand’s Sa Kaeo province.

The letter details allegations that a 13-year-old boy, who entered Thailand with the intention of selling second-hand clothes, was brutally attacked by seven Thai policemen near Rong Kloeur market on May 2.

The teenager, it is claimed, suffered a ruptured bladder in the attack. “I have not received any answer yet from Thai authorities,” said the governor’s office spokesman.

Dy Phen, director of the Cambodian-Thai Border Relations Office in Banteay Meanchey province, added that the boy had illegally concealed his wares while entering Thailand through a small border checkpoint.

Relevant Thai officials were unavailable for comment yesterday.
