SINGAPORE - A relief teacher who was filmed using crude language in class is no longer employed by the secondary school in Yishun.

This comes after a video circulating online since last Sunday (March 5) showed the teacher hurling vulgarities at a student in her class.

The teacher in the clip was seen gesturing and yelling at a girl.

At one point, the teacher could be heard shouting at the student, who also raised her voice.

Other students in the classroom appeared amused and laughed hysterically.

According to the school, the incident took place when the class was being supervised by a young, untrained relief teacher.

The school has since counselled both the student and the relief teacher involved and advised them on the appropriate classroom behaviour.

A school spokesman told The Straits Times on Monday that both parties "have regretted their actions and are apologetic". He added that the relief teacher is no longer engaged by the school.

"We are providing the necessary support to the affected students in the class and working closely with their parents," he said.
