RPF personnel S Samanta, who was killed on Monday when hawkers allegedly attacked Railway Protection Force office in Malda station premises, had died of bullet injury and not due to stones thrown by the accused, police said.

"Samanta died of bullet injury and not due to stones thrown at him by hawkers," a police officer said.

The police are investigating who fired the bullet which hit Samanta, leading to his death, the officer said.

The RPF had lodged a complaint with the police in connection with Samanta’s death, the officer said, adding that the police was investigating the matter but no arrests have been made till now.

Samanta was killed and three more RPF personnel were injured yesterday when angry hawkers attacked the RPF office in the Malda station premises, pelting brickbats and stones after one of them was barred from doing his business.

The RPF personnel asked a hawker not to sell wares at the entrance to the station, but as the hawker protested the personnel beat him up, police said.

A large group of hawkers then barged into the office of the RPF located near the station and pelted brickbats, prompting a panicked RPF jawan to fire from his rifle, police said.
