Some students of a secondary school in Katsina state were captured on camera beating up their teacher in their school.
In the video which gone viral on social media, two students can be seen beating an older man in a green jersey while their colleagues cheered them on.
The teacher later managed to extricate himself from their grasp and then grabbed one of the students.
“Are you mad?” the visibly angry teacher asked as he slapped the boy across the face.
