The Enforcement Directorate arrested former Kolkata Police Deputy Commissioner Santanu Sinha Biswas on Thursday following raids across West Bengal [1, 2].

The arrest of a high-ranking former police official signals a significant escalation in the federal agency's crackdown on corruption and extortion within the state's security apparatus. It suggests that the investigation may uncover broader networks of influence and systemic misconduct.

Federal agents conducted simultaneous raids in Kolkata and Murshidabad as part of a probe into an alleged multi-crore extortion and fraud racket [1, 2]. The operation targeted locations linked to the former top cop to gather evidence regarding the illicit financial network [1].

Biswas was taken into custody at the ED’s CGO Complex office in Salt Lake, Kolkata [2]. The arrest followed a period of questioning that lasted more than 10 hours [2].

There are discrepancies in reporting regarding the specific nature of the charges. While some reports state the arrest is tied to fraud and extortion [2], other sources describe the investigation as a land-grabbing probe [3].

The agency is currently investigating the extent of the racket and whether the former official had political connections that facilitated the alleged crimes [1, 2]. The ED has not released a detailed public statement on the specific assets seized during the raids.

The arrest of a former Deputy Commissioner indicates that the Enforcement Directorate is targeting the intersection of law enforcement and organized financial crime. By focusing on a high-profile officer, the agency is likely attempting to map out how official authority was leveraged to execute extortion or land-grabbing schemes, potentially leading to further arrests of political or administrative collaborators.
