Indore, Feb 12 (PTI): The principal of Delhi Public School (DPS) here was arrested today for alleged violation of rules, following the death of four students of the institute in a bus accident on January 5, the police said.

Deputy Inspector General (DIG) Harinarayanchari Mishra said Sudarshan Sonar, the principal of DPS, was arrested for alleged violation of rules and regulations related to transport and maintenance of school buses. Sonar was produced in a court here, which rejected his bail plea and remanded him in judicial custody till February 22.

On January 5, a bus belonging to the school had rammed into a truck at Kanadiya bypass, killing four students and the driver. On January 7, the police had arrested a DPS official and two other persons for culpable homicide not amounting to murder, cheating and forging documents after investigations revealed that the bus' speed governor was malfunctioning.

District Prosecution Officer Mohammed Akram Sheikh today said Section 188 (disobeying of orders issued by a government authority) of the IPC had also been added after a probe. Police had claimed that a forged certificate was obtained from a private firm which certified that the speed governor of the bus was working properly. Police investigations also revealed that at the time of the incident, the bus was running at a speed of 60 kilometers per hour instead of the mandatory 40 kmph limit, which meant that the speed governor had been tampered with.
