Mathura Basic Shiksa Adhikari Shyam Prakash Yadav said Headmaster Mahavir Prasad, Assistant teacher Mohar Singh and a class IV employee Jayveer Singh were suspended with an immediate effect for watching obscene videos on school's computers.
A contractual part-time teacher Praveen Kumar was fired from the job in the matter, he said.
Yadav said, on a complaint, Assistant Basic Shiksha Adhikari had gone to inspect the matter in the school where he found a video clip in Kumar's cell phone, depicting the headmaster watching the obscene videos.
