Condemning police "brutalities" on their workers, West Bengal's opposition Left Front on Monday threatened to stage protest rallies in various parts of the state.
"This has to be protested and we will do that by staging rallies on Tuesday," he said.
Protesting against the central and state policies, the Left had organised a programme during the day to submit memorandum to the district magistrates in all the districts.
Communist Party of India-Marxist state Secretary Surya Kanta Mishra said: "The Chief Minister (Mamata Banerjee) should know that when the people of the state have taken to the streets, they cannot be stopped."
Earlier in the day, police baton-charged a group of Left party supporters when they used force to try and enter the office of the District Magistrate of North 24 Parganas district.
According to police, a few policemen suffered injuries in Bankura when they tried to stop a large number of members of Leftist organisations from entering the District Magistrate's office.
