HANOI, March 16 (Xinhua) -- Border guards of Vietnam's central Ha Tinh province detained a Vietnamese man when he was transporting 3,200 pills of lab-made drugs from Laos to Vietnam, provincial border guards said on Friday.

The 32-year-old man from central Thai Nguyen province was arrested on Thursday when he crossed the Cau Treo international border gate in Ha Tinh.

Vinh confessed buying the drugs from a Lao woman. The case is under further investigation.
