Police in the southern province of Ba Ria-Vung Tau on Thursday morning brought 150 people back to a drug rehab center after a large group of 447 staged a chaotic scene and escaped last night.
Hundreds of police officers were mobilized to search for the runaways at around 8:30 p.m. on Wednesday.
The group, who entered the center in compulsory programs, reportedly assaulted several officers of the center, knocked down walls and gates and fled.
Earlier they staged a fight. When a group of officers reached the scene to end the violence, they were assaulted by dozens of inmates.
After getting out of the center, several reportedly threw stones into the center, robbed some motorbikes and broke into a local company.
Authorities said they are calling upon families of the other drug users to help bring them back to the center.
