Government Chief Whip Sobhandeb Chattopadhyay said during Zero Hour that Ghose, the former minister of Pascham Anchal Unnayan Affairs, had indulged in "mass killing with full knowledge of the former chief minister".
He demanded that Bhattacharjee be arrested and interrogated as also Deepak Sarkar, a key CPIM leader in West Midnapore district.
Ghosh was arrested on Thursday in connection with the recovery of seven skeletons from near his ancestral house in West Midnapore district on June two, after his anticipatory bail was rejected by a Midnapore court.
Public Health Engineering Minister Subrata Mukherjee rubbished accusations that the state government was pursuing vindictive politics against the CPI-M leader and wondered how Ghosh, "who was responsible for the killing of 200 people", could retain his house membership.
Membership of an MLA was cancelled on a much lighter charge during the tenure of the previous Left Front government, he told the House.
Mukherjee alleged Ghose was a minister in charge of "mass killing and supply of arms and should be given exemplary punishment." Earlier, Leader of the Opposition Surjya Kanta Mishra demanded adjournment of the House to discuss the "reign of terror unleashed by the ruling Trinamool Congress".
