Police said a Sierra Leone national, identified as Amadu Kardgo (33), was arrested by BSF jawans and handed over to police on Monday.
Police said the person was carrying a fake passport and a fake Indian visa which he could register at the Bangladesh immigration office as they had no computer or online facility. After entering the Indian side, he was trying to escape without registration at the Indian check post at Srimantapur in Sonamura subdivision.
He was found to be a drug addict, police said.
Earlier, Two South Africans were arrested in Sonamura subdivision of the district on February 16 with fake Indian currency of the face value of Rs. 60,000.
