Bengal CID raids Abhishek Banerjee's Camac Street office, Kalighat TMC HQ in Kolkata
Synopsis
West Bengal CID simultaneously raided Abhishek Banerjee's Camac Street office and the TMC's Kalighat headquarters on 9 June — both sites resisted entry until police reinforcements arrived. Abhishek, away in Delhi for the INDIA bloc meeting, had already ignored two prior CID summons in the legislator signature-mismatch case. The third notice was due at 5 pm the same day.
Key Takeaways
West Bengal CID conducted parallel raids on 9 June at the TMC party office, Kalighat and Abhishek Banerjee's Camac Street office in Kolkata.
Both sites offered initial resistance; Kolkata Police and CAPF personnel were deployed at Kalighat, while Shakespeare Sarani Police Station officers assisted at Camac Street.
The raids are linked to a probe into alleged signature mismatch of TMC legislators on a West Bengal Assembly resolution concerning Opposition-bench positions.
This was the third consecutive CID notice served to Abhishek Banerjee , who was summoned to Bhabani Bhavan by 5 pm Tuesday .
Both Abhishek Banerjee and Mamata Banerjee were reportedly in New Delhi , having attended the INDIA bloc meeting on Monday.
The Criminal Investigation Department (CID) of the West Bengal Police conducted simultaneous raids on Tuesday, 9 June at two locations in Kolkata — the All India Trinamool Congress (TMC) party office adjacent to former Chief Minister Mamata Banerjee's residence at Kalighat, and the Camac Street office from which Abhishek Banerjee, the party's General Secretary and Mamata Banerjee's nephew, reportedly operated. The parallel search operations unfolded amid a larger probe into an alleged signature mismatch involving TMC legislators on a resolution concerning key Opposition-bench positions in the West Bengal Assembly.
Resistance at Both Sites
At the Kalighat party office, CID sleuths initially faced resistance from former TMC Rajya Sabha member Subhasish Chakraborty, who identified himself as voluntarily and temporarily in charge of the premises and refused the investigators entry. The standoff ended only after a joint contingent of Kolkata Police and Central Armed Police Forces (CAPF) personnel arrived at the site, enabling CID officials to enter despite continued objections from Chakraborty and his aides.
A similar scene played out at Camac Street, where staff at Abhishek Banerjee's office initially blocked investigators. Officers from the local Shakespeare Sarani Police Station were subsequently deployed, after which the CID team gained entry and began search operations.
Third Notice to Abhishek Banerjee
Abhishek Banerjee had been summoned by the CID to appear at its headquarters at Bhabani Bhavan in South Kolkata by 5 pm on Tuesday for questioning in the signature-mismatch case — the third consecutive notice served to him in the matter. The case relates to alleged discrepancies in the signatures of certain TMC legislators on a resolution tied to important positions in the state assembly reserved for the Opposition bench.
Both Abhishek Banerjee and Mamata Banerjee were reportedly in New Delhi at the time, having attended the INDIA (Indian National Developmental Inclusive Alliance) bloc's crucial meeting on Monday.
Political Context
The raids come at a particularly sensitive moment for the TMC leadership, with both senior figures absent from Kolkata and engaged in national Opposition-level discussions. Critics argue the timing raises questions, though the CID — a state police wing — operates under the West Bengal government's jurisdiction, which the TMC itself leads. This is the latest in a series of legal and investigative pressures bearing on the party's inner circle in recent months.
What Happens Next
At the time of reporting, search operations were ongoing at both locations. It remains to be seen whether Abhishek Banerjee will comply with the CID's summons or challenge it legally, as he has done in the past. The outcome of Tuesday's raids and any material recovered could shape the trajectory of the signature-mismatch investigation significantly.
Point of View
That is a structural integrity issue for West Bengal's democratic institutions — not merely a party-politics story.
