The Enforcement Directorate has provisionally attached assets worth ₹2.78 crore linked to former Kolkata Police deputy commissioner Santanu Sinha Biswas, his family members and associates. The properties include three flats in Kolkata and land in Murshidabad. The agency alleges Biswas benefited from a network involving businessman Jay S Kamdar and Biswajit Poddar, known as Sona Pappu, through land grabbing and extortion. Biswas was arrested in May, and the money laundering investigation remains ongoing.

ED Attaches Assets Worth Rs 2.78 Crore in Santanu Sinha Biswas Land Grabbing Case

The Enforcement Directorate has provisionally attached properties worth Rs 2.78 crore in an alleged land-grabbing, corruption, and money laundering case against former Kolkata Police deputy commissioner Santanu Sinha Biswas.

The Santanu Sinha Biswas land-grabbing case has taken a fresh turn after the Enforcement Directorate (ED) provisionally attached immovable properties worth Rs 2.78 crore belonging to the former Kolkata Police deputy commissioner on Thursday, November 12, 2026.

The attachment is part of an ongoing probe into allegations of money laundering and corruption against Biswas, businessman Jay S Kamdar and alleged strongman Biswajit Poddar, also known as Sona Pappu, officials quoted by the Press Trust of India (PTI) said.

The attached properties are three flats in Kolkata and a plot of land at Kandi in Murshidabad district. The agency has identified assets linked to Biswas, his family members and associates as alleged proceeds of crime.

The ED alleged that proceeds of crime were generated by way of extortion, illegal occupation of real estate properties and unauthorised building construction involving entities controlled by Sona Pappu, Jay S Kamdar and their associates.

PTI quoted the agency in its statement as saying that Biswas allegedly received financial benefits worth several crores from private entities and businessmen in lieu of providing illegal favours during his police service.

Biswas held several important positions in the Kolkata Police under the previous Trinamool Congress government. He was also the officer-in-charge of the Kalighat police station in the area where former West Bengal chief minister Mamata Banerjee's residence is located.

Biswas, during his posting at Kalighat, allegedly developed a close nexus with Jay S Kamdar and helped him in unlawful activities, the ED said. The agency also said that Kamdar leveraged this association to wield considerable clout in the police establishment.

The ED alleged that Biswas had directly and indirectly acquired, concealed and possessed proceeds of crime to the tune of Rs 2.89 crore and above.

Sona Pappu Syndicate Faces Rs 50 Crore Allegations

Biswas was arrested by the ED in May 2026 in connection with the alleged land-grabbing racket and is now in judicial custody.

Investigators claim that Biswas colluded with Sona Pappu and businessman Jay Kamdar to illegally occupy valuable land parcels across Kolkata for a long period of time.

Biswas allegedly abused his police power to threaten and harass helpless landowners to give up their lands. The agency has estimated that the alleged syndicate earned proceeds of crime of at least Rs 50 crore from such activities.

The ED filed a charge sheet in the land-grabbing probe in July 2026, saying evidence directly connected Biswas to the alleged embezzlement of approximately Rs 3 crore.

The latest attachment of properties worth Rs 2.78 crore is another development in the agency’s bid to identify and freeze assets allegedly linked to proceeds of crime.

Kolkata Police has filed a separate case against Biswas under the Prevention of Corruption Act. The separate hearings add another layer to the allegations about his behaviour during his time in public service.

The ED’s probe is still underway into the alleged financial benefits, purchase of properties, unauthorised construction and the role of associated persons and entities.

The Rs 2.78 crore assets attached provisionally, the alleged Rs 2.89 crore proceeds of Biswas and the Rs 50 crore syndicates are all different figures that have come up during the course of the investigation.

The legal status of the attached properties and the charges against the accused will be decided in further proceedings. Sprouts News will keep following the investigation and any court actions that result.
