Four men were injured as two gangs had a gun fight involving 50 people in Hanoi early Tuesday.
The groups fought at approximately 1:30 a.m. after their members, Nguyen Kim Thang, 30, and a man only identified as Tuan had a personal conflict, according to a Tuoi Tre report.
Tuan had brought 40 of his gang members to a hotel owned by Thang's family. Tuan's gang fired gunshots at Thang's gang of 10 people, and chased the latter with swords.
Four men in Thang's group were shot. Thang has been sent to a hospital.
Tuan's group also destroyed a motorbike and a car in front of the hotel before leaving.
Hanoi police are investigating the case.
