Police in remote Ratanakkiri province have arrested five apparent Montagnard asylum seekers, including three children, local rights workers said Monday.
The arrests were made in the jungle Sunday night, where a group of Montagnards has been in hiding.
Chhay Thy, the local coordinator for the rights group Adhoc, told VOA Khmer he does not know the current whereabouts of the detainees.
Thirty-two Montagnards fled Vietnam in January, and 27 remain in hiding, he said.
Police officials say they are not arresting Montagnards, but are deporting illegal immigrant farmers from the province.
