About 20 students of Mumbadevi Vidya Mandir, Khar, were allegedly confined to the school library for the fourth consecutive day on Friday over a fee-related tussle between the parents and school management.
Senior police inspector of Khar police station, M Pote, went to the school on Friday to inquire about a complaint filed by parents on Thursday.
Parents of some of students had filed a complaint with the Khar police stating that their children had been confined in the library for three days in a row because they failed to pay the whole year's fee in advance.
Pote confirmed that he visited the school and that an FIR had been filed in the matter.
"It was a repetition of the same thing that has been happening to our children for the past three days," said Susham Shewale, a parent of a Class 9 student. "We will take guidance from the Forum for Fairness in Education and see what we should do next."
In June, the school had hiked the fees and asked parents to pay for the entire year.
When parents refused, the school returned the cheques that were payments for the quarterly fees. When the school reopened after the Diwali break on Monday, the principal warned students whose parents had not paid the entire annual sum that they would be punished if they did not do so. On Tuesday, Wednesday and Thursday 38 students were confined in the library during school hours. Some agreed to pay the entire year's fee on Friday and were allowed to attend class.
The Forum for Fairness in Education, a non-government organisation that works in the field of education, has said it plans to file a Public Interest Litigation on the unfair treatment meted out to students by schools and the government's failure to act in the matter.
