Kien Giang police have arrested three Vietnamese men accused of abducting six Cambodian people and demanding ransoms from their families.
Police said the Cambodian group entered Vietnam to find jobs a month ago. Three weeks later when they were about to return home, they met a Vietnamese man known only as Cuong.
Cuong reportedly promised to help them find work for VND300,000 (US$14) a day.
He then drove the group from HCMC to Kien Giang Province where he handed them over to Ly Hong Sinh, 56, Nguyen Van Dung, 51, and Tran Van Duong, 46.
Cuong allegedly took VND18 million from the trio and left.
The trio then locked the Cambodian group in a hotel room after failing to force them to work as offshore fishermen. They then made the abductees to call their relatives for ransoms of VND3 million each.
A neighbor contacted the police after noticing suspicious activities. All the victims have been rescued.
Police are hunting for Cuong.
