A BSF jawan has been identified as the principal accused of the firing that occurred at Sukanta More in the Debinagar area of Raiganj on Monday night.

Police have arrested Jayashri Das, the jawan’s sister, and are in search of him and some others. Senior police officers are trying to find out how a quarrel between a former tenant and the landlord’s family led to the firing which left a woman dead and two others, including a police officer, injured.

On Monday night, Sital Roy, who is a constable in the BSF, went to the house of Nikhil Krishna Majumdar, a retired deputy superintendent of police, along with some associates.

“During preliminary investigation, we have come to know Sital Roy used to stay at the house as a tenant earlier and had some problems with the house-owner. We are trying to find out what was the dispute which made him fire at the house-owner’s family,” said Arsh Sharma, the additional superintendent of police of Raiganj police district.

Sources said after reaching in front of Majumdar’s house, he called for the house owner. At that time, Rupa Adhikari, Debi Sanyal and Sujay Krishna Majumdar – the daughters and son of Nikhil Ranjan – were present at the house.

They dwell in different localities of the town and had come to see him.

Hearing Sital’s call, Rupa went out. Soon, they had a heated exchange of words which made Debi and Sujay to step out. Sujoy, who is a police officer posted in Dabgram armed police brigade on the outskirts of Siliguri, asked Sital to leave.

“Suddenly, Sital and his associates took out firearms and fired indiscriminately at the sisters and the brother. All three of them suffered serious injuries and fell on the ground,” said a police officer.

Locals rushed for help and took the trio to Raiganj Government Medical College & Hospital where doctors pronounced Debi (37), dead. Later, Rupa was referred to Malda Medical College & Hospital.

As police started investigation, they came to know that Jayashree Das, Sital’s sister, was also with him at the spot. She was soon arrested and on Tuesday, she was produced at a local court.

“The court heard the case and has sent her in police custody for 10 days. We need to interrogate her to know what led to the incident,” police sources said.

The police are also in search of Ripon Roy, another local youth, who is suspected to be involved in the incident.

Sital meanwhile, has managed to escape. The police have sealed his house in Kashibati area of Raiganj.

“We have come to know that he is posted in Punjab now. We have passed the information to his senior officers so that he is taken into custody in case he turns up at his workplace,” said Sana Akhtar, SP, Raiganj police district.
