ED Arrests Kolkata Police DCP Shantanu Sinha Biswas in Alleged Extortion Syndicate Linked to Sona Pappu

May 14, 2026 : The Enforcement Directorate (ED) has arrested Kolkata Police Deputy Commissioner Shantanu Sinha Biswas in connection with an alleged extortion syndicate linked to criminal figure Sona Pappu alias Biswajit Poddar.

Shantanu Biswas was questioned for over 10 hours at the CGO Complex in Kolkata before being taken into custody. He is expected to be produced before a court today.

The ED had summoned the officer multiple times in its money laundering investigation, but he allegedly skipped several appearances, prompting the agency to issue a lookout notice against him.

According to investigators, financial transactions linked to Shantanu Biswas and associates of Sona Pappu came under scrutiny during the probe. The officer’s name also surfaced in documents recovered from businessman Joy Kamdar, who was earlier arrested in the same case.

Last month, the ED had carried out raids at Biswas’s Fern Road residence in Kolkata as part of the ongoing investigation.
