Police in An Giang Province are investigating allegations that a local man set their neighbors on fire because he was annoyed of their loud karaoke party.
The victims of the attack were Le Huu Phuoc, 33, and Huynh Van Tam, 29, of Phu Tan District in the Mekong Delta province.
Initial investigation found that the duo were singing karaoke at home at around 7 p.m. on July 27.
Their neighbor, Ngo Van Vang, came over and asked them to turn down the volume.
After a while, Vang returned and threatened to set them on fire because they ignored his request.
Tam and Phuoc said they saw Vang throwing gasoline on them before chasing after them. He then lit them on fire, they said.
Local residents put out the fire and took them to a local clinic.
They were transferred to An Giang General Hospital with severe burns, mostly on their chests and arms.
Home karaoke is a common form of entertainment for many families in Vietnam.
Especially when combined with drinking, karaoke singing is the cause of many conflicts.
In a similar case in early June, An Giang police arrested 30-year-old Tran Ba Xuan for attacking their neighbors.
The incident happened on May 31 when his neighbor, Nguyen Van Hai, had a party and sang karaoke at noon.
After some arguing, Xuan used a machette to attack Hai and his two sons.
Another neighbor, Nguyen Van Thao, attempted to calm him down only to have his left hand almost cut off.
