Police in the southern province of Soc Trang Monday arrested an officer for allegedly beating a local man to death last month.
Danh Nhan, an officer of Nga Nam Town's police division in the district of the same name, was suspended last week along with two other officers for involvement in the death of Tran Van Du, 44.
According to initial information, on March 30, Du was escorted to police's station for allegedly attacking his mother when he was drunk.
At around 11 p.m. that day the man was found dead near the station.
An autopsy later showed that he died from a ruptured liver and blood congestion in his abdomen besides serious injuries on the back of his head.
Nhan will be investigated on charges of "deliberately causing injuries leading to death," police said.
