Prachin Buri Immigration Authorities Detain 18 Undocumented Workers
Immigration police in Prachin Buri province have arrested 18 foreign nationals found working illegally at two factories in the Si Maha Phot district.
According to a report by Matichon Online on October 27, 2026, immigration authorities in Prachin Buri province conducted an operation that resulted in the detention of 18 undocumented workers. The individuals, identified as citizens of China and Myanmar, were discovered working at two separate factory locations within the Si Maha Phot district.
For residents and expatriates in Thailand, this incident highlights the ongoing enforcement of labor and immigration laws by local authorities. The discovery of undocumented workers in industrial zones often leads to increased scrutiny of employment documentation and business compliance in the surrounding areas. Travelers and residents should ensure that all necessary identification and legal documentation are kept current and accessible, as authorities may conduct inspections to verify the legal status of foreign nationals.
At this stage, details regarding the specific charges against the workers and the factory owners remain to be confirmed. It is also unclear what legal proceedings will follow for those detained or whether the factories involved will face administrative penalties. Further information is expected as the investigation by the Prachin Buri immigration office continues.
