Pol Lt Col Benjaphol Rodsawad, a deputy police commander in the province, said that outside assistance was sought to inspect the workers and their belongings.
Sa Kaew's police force could not concurrently cope with the large number of workers and facilitate tourists, he said.
At 10am today, the workers occupied the whole area in front of the immigration office, leaving no space for foreign and Thai tourists to have their passports stamped.
The police officer said that the flow of Cambodian workers through the border gate increased after the signing of memorandum of understanding to end labour trafficking. This reduced illegal entries by Cambodian workers along the border. Meanwhile, severe drought in their country and high labour demand in Thailand encourage them to seek jobs in Thailand.
