Police in Ho Chi Minh City Saturday detained three members of a motorbike robbing group who attacked women driving alone at night.
The men, 17, 18 and 25 years old, were arrested after they robbed a motorbike and left it at a local parking lot.
They admitted to having carried out 13 robberies in the city, mostly in outlying districts. Their leader Nguyen Thuy Hoang, 23, is still at large.
Local police started investigating the group on November 28 after receiving at least five robbery reports about a group of men attacking female motorists with tear gas, electronic whips and hand cuffs.
The police have asked any victims of similar crimes to file their reports to support further investigations.
