"I challenge them (state government) to go for a CBI probe into the killing of Srinu Naidu. Everything will be clear then," he told reporters here.
His statement came a day after TMC general secretary Subrata Bakshi urged the police to look into the role of Ghosh in the incident.
Ghosh is the MLA from Kharagpur.
The Trinamool Congress have pointed fingers at Ghosh following his comments a few months back that whoever clashed with him "will have to bite the dust".
"Yes, I had said it. I had said it against the TMC, not against any individual. I had gheraoed the local police station demanding the arrest of Naidu for his illegal activities. We all know that Naidu was an anti-social and the TMC was giving him protection. The police should probe that part," Ghosh said.
