GUWAHATI – The Central Bureau of Investigation (CBI), Anti-Corruption Bureau (ACB), Guwahati, has registered a criminal case against a Senior Auditor at the Office of the Controller of Defence Accounts (CDA) for allegedly operating an organized bribery racket. The official is accused of systematically demanding “commissions” from private contractors in exchange for processing and clearing their bills.
The First Information Report (FIR), registered on February 2, 2026, follows a Preliminary Enquiry that revealed a well-planned pattern of corruption spanning 2024 and 2025.
The “Commission” Modus Operandi
The primary accused, Shri Mrinmoy Ghosh, served in the Bill Section of the CDA office in Narengi, Guwahati. His role involved the scrutiny and audit of bills submitted by Army Units and private vendors.
According to the CBI investigation, Ghosh exploited his position to demand illegal gratification ranging from 1% to 2% of the total bill amount.
- Coded Language: In telephonic conversations, Ghosh reportedly used terms like “his share,” “fixation,” or “settlement” to signal bribe demands.
- Layering Money: To avoid detection, Ghosh allegedly instructed contractors to transfer funds via UPI to the bank account of his cousin, Riktom Roy.
- Laundering Proceeds: The investigation found that these illicit funds were subsequently moved from Roy’s account to the bank accounts of Ghosh’s wife and mother to camouflage their origin.
Legal Action and Next Steps - The case has been registered under Section 61(2) of the Bharatiya Nyaya Sanhita (BNS), 2023 (Criminal Conspiracy) and multiple sections of the Prevention of Corruption Act, 1988 (as amended in 2018), including sections related to bribery and abetment.
- The investigation is being led by Inspector Biplav Sarkar of the CBI ACB Guwahati. The agency has noted that the role of Mrinmoy Ghosh’s cousin, Riktom Roy, and other unknown individuals will be further scrutinized as the probe progresses. The FIR was authorized and dispatched by R. Prakash, IPS, DIG & Head of Branch
