The two foreigners would be sent to the Goalpara Detention Camp for deportation, police spokesman Rajib Saikia said.
Meanwhile, a Gaonburah (village headman), Moijan Ali, of Soulmari under the same PS was arrested today as he had illegally issued domicile certificates to many for submitting as a citizenship proof document for the National Register of Citizens (NRC), Saikia said.
