A gang of unidentified men on motorbikes attacked and vandalised several Communist Party of India (Marxist) offices across six wards of south Kolkata and targeted the home and party office of former All India Trinamool Congress (TMC) legislator Debrabrata Majumdar in the Jadavpur area on Sunday, 20 September 2026, police confirmed. The attacks, which also involved the alleged physical assault of Majumdar's family members, have sparked sharp political accusations — with both CPI-M and TMC pointing fingers at the Bharatiya Janata Party (BJP), which has not responded to the allegations.

What Happened and Where

According to a CPI-M leader, party offices were vandalised in ward numbers 96, 99, 101, 102, 105 and 106 of the Kolkata Municipal Corporation (KMC) area. The highest tension was reported in ward 96, where Majumdar — a long-serving KMC councillor — maintains both his residence and his party office. The CPI-M's martyrs' altar in the ward was also reportedly damaged during the attack.

Unrest also flared up in ward 101 and ward 105, where fights allegedly broke out. The office of former TMC councillor Tarun Mandal was also reportedly threatened, though police intervention with batons is said to have prevented the situation from escalating further. The bike gang is also alleged to have caused disturbances in Narendrapur in South 24 Parganas district.

Family Assaulted, Police Response Questioned

The alleged attackers are said to have pushed and verbally abused Majumdar's elder brother during the raid on the former MLA's house. Majumdar's family said they called police repeatedly and that officers arrived only after an hour. Debrabrata Majumdar said: 'At least 100 people came and vandalised the house. They abused my elder brother. They pushed him. They abused me. I have never seen anything like this in my entire political career. They are all BJP supporters.'

A CPI-M worker at one of the targeted offices said: 'They tore the party flags. They abused us. They are telling us not to come here. They are all BJP. They used to be with the Trinamool.' It remains officially unclear who was behind the attacks, and the identities of the perpetrators have not been confirmed by police.

Political Blame and BJP's Silence

Both CPI-M and TMC have questioned the role of law enforcement in the incident. Allegations have been levelled against the BJP, though the party had not issued any comment as of the time of this report. The attack follows a broader pattern of political violence targeting the Left in West Bengal.

Pattern of Attacks on CPI-M Offices

This is not an isolated incident. On 15 September, several CPI-M offices in the Bali area of Howrah district were vandalised — including the Dewangazi Zonal Party Office on Panchanantala Road and the party office on Belur Station Road. The Left blamed the BJP in that incident as well; the BJP denied it. Just days later, the CPI-M office in Kodalia, ward 20 of Rajpur-Sonarpur Municipality in South 24 Parganas, was also allegedly attacked — again with the BJP named as the accused.

The Jadavpur incidents mark at least the third wave of alleged attacks on CPI-M infrastructure in the state within a single week, raising concerns about the safety of opposition party spaces in West Bengal. Whether police will make arrests — and who ultimately takes political responsibility — will be closely watched in the days ahead.
