A regional distributor of a telecom operator has been arrested in Bihar’s Vaishali district for allegedly issuing more than 700 fraudulent SIM cards that fed into an illegal SIM box network linked to at least 73 cybercrime cases nationwide. Investigators uncovered the operation following technical analysis of over 1,300 SIM cards seized from Supaul district last year, prompting coordinated search operations across 10 locations in Vaishali and Odisha’s Jagatsinghpur. Digital hardware including mobile phones, laptops, and additional SIM cards were seized during the raids as authorities worked to trace the supply chain from point of issuance to cyber fraud deployment.

Links to Nationwide Digital Arrest Operations

​The probe gained momentum when forensic reviews connected the 1,300 recovered cards to registered cyber offences across multiple states, particularly digital arrest operations where fraudsters impersonate law enforcement and government officials to coerce money from victims. Investigators suspect the clandestine SIM box infrastructure served as the core telecommunications backbone for these networks. By clustering hundreds of active cards within a single automated unit, the systems allowed syndicate operators to mask their actual physical locations and origins while routing high volumes of fraudulent calls to targeted individuals across the country.

Abuse of Retailer Credentials and Biometric Records

​Scrutiny of the supply chain led investigators directly to the Vaishali distributor, who allegedly hijacked the credentials and system logins of more than a dozen local points of sale to activate over 700 mobile connections. A significant portion of these numbers were generated without the awareness or consent of the individuals whose identities were used. Investigators are scrutinising the telecom e-KYC records alongside evidence that biometric data originally captured for unrelated administrative processes was illicitly repurposed to validate the fraudulent activations.

Multi-State Nexus Under Legal Scrutiny

​Authorities are interrogating the distributor to establish the end recipients of the 700 connections, while examining the compliance procedures, verification paperwork, and complicity of the retail outlets involved. The case encompasses penal provisions under the Bharatiya Nyaya Sanhita governing cheating, forgery, extortion, and identity theft, alongside technical offences listed under the Information Technology Act and compliance breaches under the Telecommunications Act, 2022. Forensic teams are currently processing the seized electronic equipment to map out downstream handlers and determine the full scale of the synd­icate.
