1) Check for nearby residential or commercial street cameras that may have captured the school name and bus at the exact time of the incident.

2) If it is a nearby school, observe their bus fleet. You can check the logs to see which bus was on that specific route at the time of the incident.

3)  Approach the school principal with your evidence. Present the damage to the bicycle and demand compensation (for repairs or replacement). Most schools have insurance or internal protocols to handle such claims.

4)If the school refuses to cooperate, you can file a formal complaint at your local police station for Rash and Negligent Driving under the relevant sections of the Bharatiya Nyaya Sanhita (BNS).

Is there any CC TV camera nearby? If so, you may look at the footage, if permitted. Otherwise, if you know the approximate time when the bicycle was knocked down, you can get the details of the bus from the school authorities/other drivers. You may look for scratch marks on the bus to identify. If identified, lodge a written complaint with the school demanding compensation for the damage caused. As far as speedbreakers are concerned, rules as laid down by the traffic police are to be complied with and these cannot be constructed arbitrarily.

1. Complain to the jurisdictional Police and request for obtaining CCTV recordings around the place of accident. 

2.  Based on the evidence procured through CCTV, file a complaint against the Driver and the School.

3.  The school management may come for negotiation with you to resolve the issue and for paying compensation. 

4.  In case it fails,  file a case under Motor Vehicle Claims in the jurisdictional and competent Court.

5.  For installation of speed breakers and to prevent rash and fast driving by the bus drivers, complain the same to the jurisdictional DCP (Traffic) and RTO officials.
