A video showing lower secondary students throwing chairs and tables in their classroom has been making the rounds on the Internet.
Netizens, who identified the students as being from Anglo-Chinese School (Barker Road), were shocked and angry at the students' behaviour, which showed them throwing classroom furniture as other classmates tried to leave.
Some netizens asked why a teacher was not present to stop them.
In response to queries from The New Paper (TNP), the school principal said the school does not condone the students' actions in the video, and has counselled them and meted out appropriate disciplinary measures.
"The students have expressed regret for their actions," he added.
TNP understands that the incident happened after school more than a month ago, before the start of the mid-year holidays.
The school authorities found out about it after a student from the class alerted them.
In the minute-long video, two students can be seen throwing chairs and desks across the classroom and at each other as others try to leave.
A boy then tries to restore order by telling his classmates to put the chairs and tables back, but he is shoved aside by one of the students.
Soon after, the remaining students in the class can be seen trying to rearrange the furniture.
In February, a video posted on Facebook showed a group of Secondary 3 students from another school slapping, punching, kicking and throwing chairs at a classmate.
The school principal said the six students, including the victim, had been counselled, and that the school also took appropriate disciplinary measures.
