SENIOR BJP leader Mukul Roy and three others have been booked in an FIR for the murder of Krishnaganj’s Trinamool MLA Satyajit Biswas at Hanskhali in Nadia district of West Bengal .Two of the four accused — Sujit Mondal and Kartick Mondal — being local residents, were arrested by the police on Saturday night for their alleged role in firing on Biswas as he was sitting on a chair on the dais after inaugurating the Saraswati Puja in the evening. The duo was seen fleeing by local residents from the venue on Majidpur Phulbari football ground after shooting Biswas from behind. The fourth accused is Abhijit Pandary who is absconding. Reacting to the FIR, Mukul Roy said it is politically motivated. Whenever a TMC activist is killed by their own people , CM Mamata Banerjee said the BJP is involved in the murder. “I demand an impartial probe into the murder of the MLA”, he added.“Those who have been nabbed were seen firing at my husband”, Biswas’ grieving wife Rupali said. Rupali Biswas is still in shock after sudden death of his husband.

The law enforcement agencies have alerted the entire state to ensure that the alleged culprits cannot escape to other state or flee to Bangladesh.ZEE News says Sujit is known as BJP worker in the area though BJP has claimed that both the two arrested men are TMC workers.Kartik Mondal’s family has claimed that he was there in the house at the time when Satyajit was murdered.
