The incident took place in the Sangrampur police circle of the district. Circle officer, Amethi, Lallan Singh, said that all the eight students were out of danger and recuperating at the district hospital.
Another student seated in the classroom seemingly recorded the incident on a mobile phone. The recorded clip was later shared by the official Twitter handle of the National Students' Union of India (NSUI).
