"Twenty of our MLAs reached the gate of Nabanna (Secretariat building) to protest against the issues of unemployment, farmers' distress and other issues. But the police did not let us in. They forcefully stopped us and later put us in police vans. They are not disclosing whether we are in police custody or not," Mr Chakraborty told IANS.
"The Chief Minister has fled from the city. Is she not bothered about the plight of the farmers here? She has turned the state into a prison," he added.
At least 11 peasants' wings of the Left Front in the state are scheduled to hold the "march to Nabanna" rally' in five different parts of the city.
Left Front chairman Biman Bose claimed the legislators were arrested and demanded their unconditional release.
However, the police have not confirmed the arrests.
The Secretariat has been converted into a virtual fortress with all entry points blocked alongside deployment of a large police force.
Plainclothes policemen are also on duty to thwart any untoward incident.
