A prison police officer from Vietnam's Ministry of Public Security severely stabbed two locals in the central coast, a source from the ministry confirmed Sunday.
Nguyen Ngoc Hoang, stationed in Khanh Hoa Province that includes Nha Trang resort town, stabbed two people in an area of local rent rooms on November 8.
The first injured person, Vo Dang Tien, was stabbed multiple times after asking Hoang to lower his voice. Hoang was celebrating his girlfriend's birthday party in one room while Tien was in another room.
Tien's friend, Lam Tung Huong Duong, was also stabbed when he tried to stop the fight.
Both victims were rushed to hospitals.
Local police are investigating the case.
