A total of 403 Cambodians were among 719 illegal migrant workers arrested in Thailand’s Samut Prakan province this month, according to an unofficial translation of a local media broadcast provided by the Human Rights and Development Foundation’s Migrant Justice Programme Thursday. The arrests continued a recent series of raids that is part of a broader effort to “suppress, arrest and prosecute alien workers who are working underground”, a policy adopted by the Thai government on June 2. At least 550 Cambodian migrants have been swept up in the raids so far.
