CBI raids Kolkata illegal construction sites after Calcutta HC order
Synopsis
The CBI has begun raiding illegal construction sites across Kolkata after the Calcutta High Court demanded to know why the state and the KMC had failed to act on their own. With allegations spanning thousands of crores in corruption, black money laundering, foreign currency violations, and even national security risks, this probe goes well beyond routine building violations — and the 14 October deadline for a preliminary report will test whether federal investigators can move where local authorities did not.
Key Takeaways
The CBI launched a probe into illegal constructions in Kolkata following a Calcutta High Court order dated 11 September 2026 .
The agency raided a three-storey house on Canal East Road on Thursday — an incomplete structure that is nonetheless occupied.
More than 50 illegal structures have been identified across Beliaghata , Maniktala , Rajabazar , and Canal East Road ; the KMC report flagged 42 as illegal.
Allegations include corruption worth several thousand crores , black money laundering, and illegal foreign currency investment.
The court raised national security concerns and questioned why neither the KMC nor the West Bengal government acted suo motu.
The CBI must submit a preliminary report by 14 October 2026 ; it may also form an SIT if required.
The Central Bureau of Investigation (CBI) has launched a formal probe into allegations of widespread illegal construction in Kolkata, West Bengal, acting on a Calcutta High Court directive issued on 11 September 2026. The agency raided a three-storey house on Canal East Road on Thursday afternoon, marking the first visible field action in what is shaping up to be a wide-ranging investigation.
What the CBI Found at Canal East Road
The raided structure on Canal East Road presents a stark picture: no exterior plaster, incomplete internal construction, and staircases without railings — yet the building is occupied and some rooms are fitted with air conditioning. One floor is reportedly used for commercial purposes while the upper floors house residents. CBI officials climbed the building, spoke with local residents, and collected relevant information. It remains initially unclear what specific allegations attach to this particular structure.
Scale of Alleged Illegal Construction
The investigation covers alleged illegal constructions spread across Beliaghata, Maniktala, Rajabazar, and Canal East Road in Kolkata — more than 50 structures in total, according to reports. A Kolkata Municipal Corporation (KMC) report had flagged 42 constructions as illegal, and a case was subsequently filed in the High Court based on that report. Crucially, it is alleged that demolition orders for these structures were issued earlier but never executed — prompting the court's intervention.
Allegations and National Security Concerns
The scope of the allegations is significant. Alongside corruption reportedly worth several thousand crores of rupees, there are claims of black money laundering and the illegal investment of foreign currency in the construction business. Construction without mandatory permissions is also alleged. The court was further informed that the situation poses a risk to national security — an assertion that elevated the urgency of judicial scrutiny.
What the Calcutta High Court Ordered
The division bench of the Chief Justice of the Calcutta High Court passed the CBI probe order on 11 September 2026, questioning why the state administration had not acted on its own. The bench pointedly asked why a suo motu inquiry had not been initiated by the KMC or the West Bengal government over such an extended period. The court has also granted the CBI the option to constitute a Special Investigation Team (SIT) if deemed necessary, and has directed the agency to submit a preliminary report by 14 October 2026.
What Comes Next
With the CBI now in the field and a court-mandated deadline of 14 October 2026 for a preliminary report, the pace of the investigation is likely to accelerate. The question of political accountability — and whether state or municipal officials face scrutiny for alleged inaction — is expected to become central as the probe unfolds.
Point of View
If substantiated, transforms this from a municipal enforcement lapse into a federal law-enforcement priority. The real test will be whether the CBI's 14 October preliminary report names individuals or merely maps structures — because accountability, not cartography, is what the court appears to be demanding.
