Authorities in the central region's Da Nang city are investigating an incident in which four night watchmen allegedly beat up a student so badly that the skin on his head was torn and his body was burned in several places.
It is reported that the watchmen, after some argument with four students who'd rented a local house, lashed 19-year-old Tran Van Thi with a cane until his skin on his head tore.
It also appears that Thi was then sprayed with tear gas and burned with a taser.
Two other students Nguyen Van Canh, 22, and Duong Dang Hoang, 23, were also beaten and burnt when trying to stop the watchmen.
Thi has been admitted to the Da Nang Hospital for treatment.
Police found dried blood all over the room, a piece of cane and a name card apparently belonging to one of the watchmen, Nguyen Ngoc Thien. Police are looking for the watchmen.
