Synopsis
A three-time TMC councillor's arrest over a sexual assault complaint is the fourth such action against a KMC councillor in just 72 hours — and it lands the same week Firhad Hakim quit as Kolkata Mayor. The cluster of arrests and the mayoral exit point to an unusually rough patch for Trinamool's grip on civic Kolkata.

Biswajit Mondal , TMC councillor from Ward 114 of KMC, was arrested on 4 June by Regent Park Police.
The complainant alleges sexual harassment in March 2024 and again on 9 May , plus threats and obscene language.
She claims her first complaint in 2024 saw no action, allegedly due to Mondal's ruling-party ties.

Kolkata Police on Thursday, 4 June, arrested Biswajit Mondal, a three-time Trinamool Congress (TMC) councillor from Ward No. 114 of the Kolkata Municipal Corporation (KMC), in connection with a sexual assault and harassment complaint filed by a woman. The arrest, executed by the Regent Park Police Station, takes the count of TMC councillors taken into custody in the past three days to four.
Key allegations against the councillor
According to city police sources, the complainant accused Mondal of molesting and sexually harassing her on two separate occasions — first in March 2024 and again on 9 May this year. She also alleged that the councillor used obscene language and issued threats against her.
The woman has claimed that she approached the police after the first incident in 2024, but reportedly no action was initiated at the time, which she attributed to Mondal's links with the ruling party in West Bengal.
How the case was registered
After the alleged second incident in May, the complainant returned to the Regent Park Police Station. This time, an FIR was registered, an investigation was launched, and Mondal was arrested on Thursday morning.
Fourth TMC councillor held in three days
The arrest is part of a wider sweep involving KMC councillors. On 2 June, TMC councillors Sachin Singh (Ward 36) and Arjit Das (Ward 106) were arrested on charges of corruption and extortion. On the night of 3 June, Mahesh Kumar Sharma, councillor of Ward 42, was arrested on similar charges.
Mayor's resignation adds to turmoil
In a parallel development, former Minister Firhad Hakim resigned as Mayor of the KMC on Wednesday. According to TMC sources, Hakim, who is the Kolkata Port MLA, stepped down after consulting party supremo and former Chief Minister Mamata Banerjee.
His resignation came the same day several Trinamool MLAs attended an administrative meeting at the state secretariat Nabanna, called by Chief Minister Suvendu Adhikari. Hakim quit the mayoral post after returning from that meeting.
What happens next
Police are expected to produce Mondal before a city court, with further investigation underway into the sequence of complaints filed by the woman. The cascading arrests and the mayoral exit signal an unusually turbulent week for the TMC's hold over civic administration in Kolkata.
Point of View
Paired with the Mayor's resignation, is not routine policing — it is a political signal. The complainant's allegation that her 2024 complaint was buried due to party muscle is the most damning thread, and it deserves an independent timeline review rather than a fresh-FIR narrative. If TMC's civic machinery in Kolkata is being cleaned up, the test will be whether scrutiny extends beyond ward-level councillors to those who shielded them. Otherwise, this risks being read as selective housekeeping rather than accountability.
