Talking to a reporter from Lao Dong Newspaper, Mr. Hoang Nghia Thai - Chairman of Thai Hoa Ward People's Committee - said that the initial determination was that the cause was that a person sitting in a car used a phone to record the scene of a group of young people burning fireworks to celebrate the opening of N.O. restaurant. in the area on the evening of November 10.
"When they discovered the clip, the group of young men asked the person in the car to delete the video. However, this person did not agree, and the two sides exchanged words, leading to the above incident" - Mr. Thai informed.

Immediately afterwards, Thai Hoa Ward Police arrived at the scene to stabilize the situation, invite the relevant parties to work, and extract camera footage and take statements to verify the cause and clarify whether the act violated the law or not.
