The ugly face-off between the CBI and the West Bengal government took a drastic turn on Sunday evening with the dramatic arrest of a CBI team that had arrived in Kolkata to question the city's police chief.

As the virtual no-holds-barred clash played out, West Bengal Chief Minister Mamata Banerjee staged a sit-in, accusing the Prime Minister Narendra Modi-led central government of attempting a coup to destabilise the state. 

The crisis escalated after the state police stopped the federal probe agency's attempt to question city police commissioner Rajeev Kumar in connection with the Saradha ponzi scam case.

How the crisis unfolded 

On Sunday evening, officers from the Central Bureau of Investigation (CBI) arrived at the the official residence of the commissioner in the heart of the city. CBI sources had said a day earlier that they were "looking for" him, hinting that he might be arrested if he failed to respond to the CBI's summons.

It all began around 6 p.m., when CBI officers, led by its deputy superintendent Tathagata Bardhan, were spotted near Kumar's residence, but within a few minutes some senior Kolkata police officers rushed there and were seen having animated discussions with the federal team.

Kumar, a 1989 batch IPS officer, headed the Special Investigation Team set up by the Banerjee government after the Saradha ponzi scam came to light in 2013, a year before the CBI took up the case on Supreme Court order.

The drama intensified near Kumar's residence around 7 p.m., as three deputy commissioners of city police and some officers of the anti-rowdy section reached the spot, following which there ensued a scuffle between the CBI team and cops.

The five CBI officers including Bardhan were bundled into three vehicles and taken to the Shakespeare Sarani police station.

They were released later in the night.

CBI Joint Director Pankaj Srivastava said his officers went to Kumar's residence to question him, but were stopped from entering the house.

Meanwhile, the Central Reserve Police Force troopers have been deployed at the CBI headquarters at CGO Complex as also at its city office Nizam Palace.

As the CBI sleuths approached Kumar's Loudon Street home, they were stopped by city police personnel, who also forcibly took five federal probe agency officers to a police station.

The Chief Minister, who had extended support to Kumar earlier in the day, rushed to his house and was closeted with other top officers, including state police Director General Virendra.

As she came out of Kumar's residence after over an hour, Banerjee alleged that National Security Advisor Ajit Doval was giving instructions to the CBI at the behest of Modi and BJP President Amit Shah.

"I am sorry to say National Security Advisor Ajit Doval is giving instructions to the agency. He is implementing what PM Narendra Modi is asking for," Banerjee said.

"I will start a dharna (sit-in) at Dharamtala area to save institutions, constitution and the federal structure of the country. This is a satyagraha," she said.

Minutes after she began the sit-in, the police commissioner and other officers, state ministers and Trinamool leaders joined her, and scores of ruling party activists converged in the area from Kolkata and nearby districts.

Crucial cabinet meeting today 

Banerjee said a meeting of the state cabinet would be held on Monday at the sit-in venue to ratify the state budget slated to be presented during the day.

Banerjee said she would skip Assembly proceedings, but the House would continue as usual.

Banerjee also alleged CBI officers came to Kumar's residence without any search warrant to conduct a secret operation.

"You are coming to the commissioner's residence without any warrant to conduct a secret operation. It is (nothing but) instruction from Narendra Modi and Amit Shah."

"There is a constitutional break-down and they are trying to organise a coup to destabilise the state. They are trying to run a parallel administration," she told reporters outside the Commissioner's house.

"I have come here because I have a constitutional and personal responsibility to give protection to my forces," she said.

In a rare exhortation, Banerjee appealed to all security forces to be together and condemn the attitude of the Modi government.

She called the developments a 'blow' to the country's federal structure, and claimed that the Supreme Court in its judgement had said both central and state agencies can discuss mutually if they have any queries.

Addressing the media at the sit-in venue, Banerjee said a large number of opposition leaders have telephoned her to back her movement.

"Leaders of various opposition parties, including Akhilesh Yadav (Samajwadi Party), Mayawati (BSP), Tejashwi Yadav (RJD), Chandrababu Naidu (TDP), Omar Abdullah (NC), Ahmed Patel (Congress) and M K Stalin (DMK), have called me to extend their solidarity and support," she said.

Trinamool spokesperson and Rajya Sabha MP Derek O'Brien said his party would raise the matter in Parliament on Monday.
