Kolkata, Feb 8 (PTI) The West Bengal CID grilled BJP Lok Sabha MP from Ranaghat constituency Jagannath Sarkar on Saturday in connection with its ongoing investigation into the killing of Trinamool Congress MLA Satyajit Biswas, sources said.

The BJP leader was grilled for nearly four hours at Bhabani Bhaban, the CID headquarters in the city, they said.

In January, a division bench of the Calcutta High Court granted Sarkar an interim protection from arrest till February 28. The high court, however, while hearing his anticipatory bail plea, directed Sarkar to cooperate with the CID in its probe into the murder of Biswas.

Satyajit Biswas, who was a TMC MLA from Krishnaganj Assembly Constituency in West Bengal's Nadia district, was shot dead during a cultural programme there in February last year.

Biswas's family members had lodged complaint against 43 people including BJP leaders Mukul Roy and Jagannath Sarkar.
