Hours after the West Bengal police booked BJP leader Mukul Roy in the FIR regarding the murder of Trinamool Congress MLA Satyajit Biswas, the senior BJP leader has slammed the TMC saying that when anybody is killed in West Bengal, the state government tries to implicate BJP leaders. Mukul Roy, a former TMC MP, demanded that the probe should be done by an independent agency. Mukul Roy also attacked West Bengal Chief Minister Mamata Banerjee and said that she is scared of BJP's rising popularity in the state and he has been named in the FIR for this murder only on orders of Mamata. Biswas was shot dead in Nadia district of West Bengal by some unidentified assailants.
