Do I have go to court for bail if bailable arrest warrant is issued

I used to be the vice principal of a private school around 2 years ago. There were several students who had not paid their fee past the due date despite several oral and written reminders to them and to their guardians. So one day after morning assembly the defaulting students were made to stay back in a shaded place (basketball court) for 4 hours. They were allowed to go for bathroom and drink water and were released at lunch time. One of the students was there by mistake, as his fee had been paid but due to a clerical error his name had also come up in the defaulters list. Later his guardians came to office and myself andd principal apologised profusely to them but the guardians went ahead and filed a criminal case against us. Now a bailable arrest warrant has come out against me and principal. Do i need to go to court and secure a bail? The kid was not abused verbally or physically, not even hit or slapped. And we later admitted our mistake and apologised for it also. Pls advise.
