Initial information, the incident occurred at around 7:50 p.m. at the house of Mr. Hoang Van Chung (Vien village, Bang Thanh commune). At that time, Mr. Chung's family prepared three trays of rice for 20 people to eat.
The wooden floor over 3 meters high suddenly broke and everyone fell to the ground below. The two people suffered serious injuries related to the spine and broke arms and were transferred to Bac Kan General Hospital for emergency treatment. 4 slightly injured people were taken to Pac Nam Medical Center for treatment.
At the scene, many wooden boards were damaged by termites and broke after falling. Mr. Chung's house is designed according to the traditional architecture of the Tay ethnic group: the lower part is built with bricks as a warehouse, the upper part is surrounded by wood and the floor is a living space.
According to the leader of the People's Committee of Bang Thanh commune, the initial cause may be that the main crossbars are damaged by termites and cannot withstand the load when many people are sitting together.
After the incident, the locality initially provided the two seriously injured people with VND2 million each, and the remaining 4 people with VND500,000 each.
