Kolkata Police's Detective Department (DD) has taken charge of the investigation into violent clashes that erupted outside the Kalighat residence of All India Trinamool Congress (TMC) National General Secretary and Diamond Harbour MP Abhishek Banerjee on the intervening night of 6–7 November 2026. The escalation, which prompted baton charges by police, has since resulted in three arrests and the registration of four First Information Reports (FIRs).

Detective Department Steps In

On Tuesday morning, Detective Department officials visited the site near Kalighat Police Station to reconstruct the sequence of events, a standard procedure in cases involving significant public disorder. The takeover signals that the probe has moved beyond routine station-level handling to a more specialised investigative framework.

The three arrested individuals — Muhammad Tauqir Alam, Muhammad Ershad, and Srideep Das — remain in police custody. All three are reportedly associated with the TMC faction led by former West Bengal Chief Minister Mamata Banerjee and her nephew Abhishek Banerjee.

Four FIRs Filed, Abhishek Named in Two

A total of four FIRs have been registered at the Kalighat Police Station. Two were filed suo motu by the Kolkata Police itself, while a third was based on a complaint by the Diamond Harbour MP. The fourth FIR was lodged by a local woman and Bharatiya Janata Party (BJP) activist Guria Hari. Notably, Abhishek Banerjee has been named in two of the four FIRs — a development that adds political weight to the incident.

What Triggered the Clashes

The violence broke out during celebrations marking Abhishek Banerjee's 39th birthday on the night of 6 November. Local residents and BJP workers alleged that roads in the area were blocked for the event, causing inconvenience to idol-makers and devotees collecting Kali idols ahead of Kali Puja.

TMC activists, however, disputed this account. They alleged that BJP workers launched an unprovoked attack while the birthday celebrations were proceeding peacefully and without causing disruption to others. Both versions remain contested, with investigation ongoing.

Police Deploy Force, MP Confronts Officers

The situation escalated to the point where a large police contingent was deployed and officers resorted to baton charges to disperse the crowds. Several individuals from both groups sustained injuries. At the height of the tension, Abhishek Banerjee was seen in a heated exchange with police officers at the scene — a visual that drew significant attention.

Political Significance

This is the latest in a series of confrontations between TMC and BJP workers in West Bengal, a state where both parties have clashed repeatedly over territory and public celebrations. The fact that the incident unfolded outside the home of one of TMC's most prominent leaders — and that he now figures in two FIRs — could add pressure on the ruling party in the run-up to future electoral contests. The Detective Department's involvement suggests authorities are treating this as a politically sensitive case that warrants more rigorous scrutiny.
