More than 20 people have been arrested in specific cases of assault on police officers and destruction of government property in Kolkata and Howrah during the BJP's ‘Nabanna Cholo’ march. The saffron camp, however, has maintained their stance that none of their workers were involved in violence.

BJP supporters indulged in pitched clashes with police, hurled stones at them, set fire to a vehicle, and destroyed a kiosk, while officers used batons and water cannons to disperse the demonstrators.

The central agency - which wanted to question Maneka Gambhir in connection with the coal smuggling case - has issued a fresh summons, news agency PTI said.

The BJP said the move to pass a resolution against federal agencies in the assembly is an indicator of the TMC’s disregard for the nation’s laws

Maneka Gambhir was on Saturday stopped by immigration officials from boarding a flight to Bangkok, where her parents live. She was asked to wait, and later an ED officer from the central agency's Kolkata office reached the airport and handed Gambhir the notice.

The BJP has made several arrangements to ensure a huge turnout for the rally for which the administration has not granted permission and some untoward incidents during the day would be not unlikely.

A video shared by news agency ANI shows visuals from Golf Green and Lake Gardens area of Kolkata in waterlogged condition. Commuters on cycles could be seen facing difficulty in paddling on roads inundated with water.

Thousands of BJP supporters from across the state started arriving in Kolkata and neighbouring Howrah on Tuesday morning to take part in the saffron party's ‘Nabanna Cholo Abhijan’.

Adhikari was among several BJP leaders detained on their way to the secretariat ‘Nabanna.’ The Bengal unit of the BJP has also shared video footage of police thrashing BJP workers.
