They were protesting alleging that the proper treatment was not being provided to a four-year old handicapped girl of another school.
The manager and principal of a private school in Raal and two others were arrested and booked under IPC sections 186/147/353, Dy SP Jagdish Singh said.
The trouble started when the school principal and manager along with over 100 children started shouting slogans against doctors of the district hospital alleging that proper treatment was not being provided to the girl of Rajkiya Shishu Sadan, who received burn injuries last Friday.
"On the basis of the probe conducted by SDM Shalini Singh, the report for suspension of three staff members, including Superintendent of Shishu Sadan was sent by District Magistrate earlier to Government," he said claiming that the best possible treatment is being given to the girl.
