Siliguri, Dec. 5: Around 50 teachers of Delhi Public School demonstrated in front of a police station for 12 hours today, demanding the arrest of the driver and the owner of the bus that had mowed down their colleague on Saturday. The driver was picked up in the afternoon.

The protesters in front of the Pradhanangar police station alleged that the cops had failed to pick up the errant driver even after two days of Amir Rai’s death.

“What is astonishing is that the driver was not arrested though the bus plied today,” said S.K. Dubey, a senior teacher of DPS, who had been demonstrating in front of the police station since 9am.

Rai, who taught math and music at DPS, was on his way to school at Dagapur on his motorbike when the bus hit him from the rear on Hill Cart Road. His helmet fell off and Rai succumbed to his injuries on way to the hospital.

After the police picked up the driver around 3.30pm, the protesters demanded the arrest of bus owner Om Prakash Agarwal. The teachers withdrew the protest around 9.30pm after the police promised “positive action” in the next two days.

Additional superintendent of police, Siliguri, Amit P. Javalgi said: “The teachers and some other officials of DPS met me, demanding that the owner should be arrested. We are investigating the case.”

Agarwal could not be reached as his cellphone was switched off.
