He also appealed to the council members not to hinder the security screening of their personal staff and party workers who come to the Legislature premises.
"A meeting of senior police officials was held and they have apprised me of the prevalent situation. The Vidhan Bhavan (Legislature building) and Mantralaya (the secretariat) are the top most targets of terrorists," Nimbalkar said in the Upper House.
He was speaking in the House after the Monsoon Session of Maharashtra Legislature began today.
"While all other measures to ensure security of the premises will be taken, the legislators should also do their bit as the lives of many people may be at risk," Nimbalkar said.
