Banerjee alleged that a group armed with weapons entered the office around 4.30 am, assaulted staff, smashed furniture and electronic equipment and took away items including a television, printer and air purifier. He also accused Kolkata Police of failing to respond for nearly two hours despite repeated calls and emails from TMC workers and lawyers.
The BJP denied involvement, with Baranagar MLA Sajal Ghosh saying no BJP worker had taken part in the incident. Police later detained six people, according to reports. The CCTV footage circulated by the TMC could not be independently verified.
Banerjee, who was in New Delhi when the incident took place, posted videos of what he described as the aftermath on X and sought intervention from West Bengal Governor Om Birla, Union Home Minister Amit Shah, Prime Minister Narendra Modi and the Calcutta High Court.
“This is what the BJP has done to my party office in the early hours of this morning,” Banerjee wrote, asking whether the Governor, the Union Home Minister and the PMO would act or “continue to look the other way”.
He also appealed to the judiciary, particularly the Calcutta High Court, to take note of the incident and uphold the rule of law in the state.
Taking direct aim at Chief Minister Suvendu Adhikari, Banerjee asked why he was “so scared of the Trinamool Congress and of me” that his government had to resort to intimidation. He said treating the Opposition through “violence, vandalism and intimidation” left the chief minister with no “moral authority” to remain in office and demanded his resignation.

This is what the BJP has done to my party office in the early hours of this morning.
Will the Governor of WB act? Will the Union Home Minister act? Will the PMO act? Or will they continue to look the other way?

Banerjee later linked Thursday’s incident to the demolition of his party office in Amtala in July, claiming both offices had been vandalised or ransacked within a month.
“BJP’s ‘Good Governance’. Double Engine style. Vandalism. Violence. Lawlessness,” he wrote, alleging that police and BJP workers appeared to fear neither the law nor the judiciary.
The latest confrontation follows a series of disputes surrounding the Camac Street premises. In late August, Kolkata Municipal Corporation officials, backed by police, removed a TMC hoarding that civic authorities said had been put up without authorisation.
Banerjee and TMC Rajya Sabha MP Derek O’Brien subsequently accused officials of trespassing and manhandling. Police later named them and others in an FIR over alleged obstruction. A fire-safety inspection of the premises followed, which Banerjee described as part of a campaign of political harassment.
The Amtala controversy has also remained unresolved. On July 18, the district administration partially demolished the multi-storey building housing Banerjee’s constituency office, saying it had been constructed without an approved plan and that notices issued over the alleged violation had gone unanswered.
Banerjee described the demolition as “bulldozer justice” and alleged that police and BJP workers removed laptops, files and furniture while the matter was before the High Court. The administration maintained that the action was restricted to violations of building regulations.
The political stakes are high. The BJP’s victory in the 2026 Assembly election ended 15 years of TMC rule and brought Adhikari to power as chief minister. Banerjee, the nephew of former chief minister Mamata Banerjee, has since emerged as one of the principal faces of the Opposition in the state.
He has repeatedly accused the new government of using police and civic agencies to target him and the TMC. The BJP, in turn, maintains that municipal, building and fire-safety rules are being enforced and that the previous government had allowed violations to go unchecked.
The dispute over the Camac Street office now adds another confrontation to an increasingly bitter political battle between the ruling BJP and the TMC.
As of Thursday morning, there was no independent confirmation of the alleged attackers’ political affiliation. The government had also not issued a detailed response to Banerjee’s demand for the chief minister’s resignation.
