Both the students had allegedly left the school premises without informing the authorities.
In shocking camera footage from Bihar, the director of a school is seen lying prone on the ground, trying to protect himself as he is beaten mercilessly by a mob.
Devendra Prasad was attacked allegedly after two students of his "Devendra Public School" were found dead in a ditch.
He died in hospital soon after. His daughter alleges that the assault took place in front of the police and they did nothing to save him.
"My father went to the police station and took the police there. When the mob attacked him, the police officer did not intervene. An entire group of policemen could not save him," said the teen.
The disturbing footage shows the attackers repeatedly kicking and beating Mr Prasad with sticks for several minutes.
Earlier in the day, the bodies of two students, Ravi Kumar and Sagar Kumar, aged around 7-8 years, were recovered from a ditch near a construction site close to the river. As news of the deaths travelled, the villagers vandalized the school and torched two rooms and some cars using gas cylinders.
"The bodies were found in a ditch near a road that was under construction. The mob trashed the school, beat the principal and then started beating up the director," said senior police officer Sanjay Kumar.
