Prosecutors in the southern province of Dong Nai have charged a police officer for shooting his boss to death at work following a fight.
Captain Ngo Van Vinh, 39, formerly of the Suoi Tre Unit of the Dong Nai Traffic Police Division, faces a jail term of between six months and three years.
Prosecutors said Vinh and his co-workers were drinking at a karaoke parlor in Long Khanh Town on the afternoon of September 22, 2013, when they encountered Major Tran Ngoc Son, 39, deputy head of the Suoi Tre Unit, and his friend Truong Thanh Chi in a nearby room.
After the two groups met, Chi and Vinh got into an argument.
Chi reportedly hit Vinh in the face with a beer bottle.
After the fight, Vinh grew angry with Son for failing to intervene in Chi's attack.
Vinh and Son quarreled. Vinh then went back to his office, grabbed a pistol and waited for Son at the office.
At around 5 p.m. that day, Son returned to work and challenged Vinh to a fight. He allegedly punched Vinh in the face three times, drawing blood.
Vinh then reportedly drew the pistol out and fired.
When other officers heard the shots and rushed to the site, they found Vinh bloodied and Son mortally wounded. Senior-lieutenant Doan Thanh Phu was found lying in a pool of blood.
The trio were rushed to Long Khanh General Hospital, where Son died at 7:40 p.m. of an aortic rupture.
Phu and Vinh were transferred to Dong Nai General Hospital for further treatment.
Doctors said Phu was shot once in his buttocks and once in the groin; Son had been shot in the torso.
Vinh had sustained a laceration to this head. Authorities say he may have been grazed by an errant bullet.
Vinh's body was addled with other beating-related injuries.
After treatment, Phu was declared 15-percent disabled and Vinh 40 percent.
Vinh was arrested shortly after he was discharged from hospital. Before his arrest, the Dong Nai Police Department suspended Vinh from his post and stripped him of his military rank.
Investigators said Vinh was injured during a struggle with Son; Phu was shot while trying to intervene in the scuffle.
Following the incident, Lieutenant-colonel Pham Hong Minh, head of the Suoi Tre Unit, was removed from his post and transferred to another job.
A number of other officers involved in the case have been punished based on the degree of their involvement, the Dong Nai Police Department said without elaborating.
