Police in West Bengal on Sunday arrested two persons in connection with the killing of Trinamool Congress MLA Satyajit Biswas from Nadia district.

The two, identified as Kartick Mondol and Sujit Mondol, were arrested a day after they were detained from Majhdia after the killing of the TMC legislator.

The police had on Saturday also registered an FIR against Bharatiya Janata Party (BJP) leader Mukul Roy in connection with the incident. Roy, a former TMC MP, had in 2017 joined the BJP.

Biswas, a popular Dalit leader and an MLA from Nadia’s Krishnaganj constituency, was shot dead by unidentified assailants while attending a Saraswati Puja programme in Nadia’s Fulbari in Krishanganj tehsil on Saturday evening.

The assailants had fired multiple shots from point-blank range before escaping in the chaos that followed.

Reports say that the Biswas bodyguard and the Officer-In-Charge (OC) of Hanskhali Police Station have been suspended.

According to locals, there was “constant load shedding during the programme”.

The killing of the TMC leader has opened a new front between TMC and the BJP. The TMC has accused the BJP of orchestrating the murder while the saffron party has blamed the murder on the TMC’s internal feud.

While the state government has already ordered a probe by Criminal Investigation Department (CID) probe, BJP has demanded a Central Bureau of Investigation (CBI) probe.

Quoting BJP leader Sayantan Bose, NDTV reports, “I think it would be best to have a CBI probe because the CID will not be able to unearth the truth as Satyajit Biswas is the victim of intractable clash.”

The Hindustan Times reports that the residence of a BJP worker was vandalised by TMC supporters over the killing.
