A CAMBODIAN migrant worker who was arrested by Thai authorities on Saturday after he was suspected of spying may be released on Friday, Foreign Minstry spokesman Koy Kuong said yesterday. Yean Vuth, 46, was arrested in Thailand’s Sa Kaeo province as he was walking past a military base. “It is not 100 percent that he will be released, but pending an investigation and with intervention from our officials, he may be free by Friday,” Koy Kuong said, and Cambodian consular officials were monitoring the prisoner’s case closely.
