Three of the seven students suffered head injuries and had to get stitches at a local hospital.

The incident took place at Bandel’s Don Bosco School when the students were decorating their classroom for the celebrations and playing with foam spray.

According to the police complaint lodged by the parents of the students, Vice-Principal Subir Mondal entered the classroom, immediately snatched the foam spray from the students and hit them with it. Three students — Ishan Das, class monitor Subrata Rudra and Aritra Sengupta — received serious injuries.

“The students were playing with foam spray and spraying the liquid on each other. At that instance, Father Mondal entered the class and tried to settle the students. In his attempts to put the class in order, he snatched the can and threw it. Unfortunately it hit the two students,” said Father K Matthew, the principal of the school, who termed the injuries as “minor”.

He said the school had forwarded its report to the Don Bosco Mission. “We will wait for the response of the authorities on the incident,” he added.

Kaushik Das, father of Ishan, said his son had to get two stitches on his head. “I lodged the complaint with the police because I want the vice-principal to be punished so that such incidents are not repeated,” Das said. “My son is the monitor of the class and he was trying to calm down the excited students,” he added.
