The incident took place on Saturday in Mahbubnagar.
The boy had allegedly clicked on a mobile phone his math teacher sleeping in class on Thursday and forwarded it to the District Education Officer on WhatsApp. The teacher was suspended, which is believed to have incensed other teachers in the school.
On Saturday, a group of teachers contacted the police.
Denying that the boy was beaten, the police claim he had been caught drinking on school premises.
''Even if the boy was consuming alcohol, the teachers cannot get him beaten up so badly. They have colluded with the police,'' said Achyuta Rao, a child rights activist belonging to Balala Hakkula Sangam.
