A high school teacher in the north-central Vietnamese province of Nghe An had had his nose broken by the older brother of a misbehaving student.

Dang Minh Thuy, 40, a physical education teacher and the homeroom teacher of class 9D at Tan Thanh High School in Yen Thanh District, was hospitalized for his injuries, the school board confirmed on Thursday afternoon.

Thuy was attacked by N.V.D., older brother of N.V.P., a student in class 9D.

The victim shared that the attack was in retaliation for his imposing disciplinary action upon P. for burning paper in the classroom on Tuesday.

The teacher sent a formal letter inviting P.’s parents to the school to discuss his bad behavior.

At around 9:30 am on Wednesday, D. and another man arrived at the school to talk with Thuy about the incident.

During their conversation, D. suddenly threw a punch at the teacher, knocking him to the ground. 

Thuy was later brought to a local general hospital by his colleagues.

According to Tran Ngoc Duc, doctor at the infirmary, X-ray results showed that the victim‘s nose was broken.

It is unclear why D. attacked Thuy, Phan Van Quang, vice-principal of Tan Thanh High School, stated.

Some students in class 9D said that Thuy had hit P. before as a warning for his wrongdoing, Quang added.

Thuy has been teaching for over 10 years, according to the vice-principal.

Police officers in Yen Thanh District are investigating the case.
