Police operation in Tupamari uncovers large cache of financial instruments and digital files
Assam police on Wednesday said they recovered a substantial quantity of financial instruments and electronic evidence during a raid at No. 1 Tupamari village in Kamrup district, part of the policing area that serves peri-urban Guwahati. The seizure included 69 ATM/debit cards, 63 bank passbooks and a mobile device containing files linked to a suspected online gaming and chip-selling operation, officials reported.
The operation was carried out after what police described as "credible information" and was led by Boko–Chaygaon Co-District Superintendent of Police (CDSP) Jankishore Gogoi, APS, together with Tupamari Police Outpost In-Charge Champak Kalita and Nagarbera Police Station Officer-in-Charge Harjit Das.
Digital evidence points to a specialised application
Investigators said they recovered a mobile phone in the residence of Rafiqul Islam, son of Mubark Ali. The device reportedly contained the ChipSeller application and related files, including ChipSeller.apk and base.apk. According to police, the app data displayed records of chip transactions — purchases and sales — and an aggregate earnings figure of ₹3,87,499.
"WhatsApp and Telegram conversations related to chip transactions, payments and payout accounts were found on the phone," police said.
Along with conversational logs, officers said they recovered UPI information, QR codes and other payment-related material that will be examined to trace the flow of funds and establish links across accounts. The seized passbooks included 58 Bank of India passbooks, police added.
Investigative priorities and wider policing context
Police reported that the digital and financial material recovered is being forensically scrutinised to determine the scale of the alleged operation and to identify additional individuals who may be connected to the network. Further action, including possible arrests and charge-sheets, will depend on the results of that examination.
The raid in Tupamari forms part of a series of operations in the Boko–Chaygaon policing belt. Officials said CDSP Jankishore Gogoi and teams earlier conducted coordinated anti-narcotics drives across several police station areas — including Nagarbera, Goroimari, Sonatoli Police Outpost, Chaygaon, Mandira Police Outpost and Samaria Police Outpost — which led to multiple arrests in suspected drug-related cases. The Tupamari action, police said, extends this enforcement focus to alleged financial and cyber-enabled illegalities.
Local implications
For residents of Guwahati and surrounding semi-urban localities, seizures of large numbers of ATM cards and passbooks underline the risks of bank-account trafficking and money-mule networks that can be exploited by organised groups. Police said establishing ownership of the recovered cards and passbooks and tracing payment flows will be key to determining whether customers were defrauded, accounts were misused without consent, or individuals acted as intermediaries for the alleged gaming operation.

| Item | Quantity |
|---|---|
| ATM / debit cards | 69 |
| Bank passbooks | 63 (58 Bank of India) |
| App-reported earnings | ₹3,87,499 |
| APK files recovered | ChipSeller.apk, base.apk |
Police said the material recovered will be analysed to map transactional links, identify payout channels and determine whether the alleged activity involved local residents as account holders or third-party facilitators. The investigation will also assess whether the ChipSeller application formed part of a wider online platform operating across districts.
Officials cautioned that while the seizure represents significant evidence, conclusions about criminal liability will follow only after forensic examination and verification of ownership of financial instruments. The probe is ongoing and police said they will share further details as investigations progress.
The episode highlights challenges for law enforcement in confronting schemes that straddle mobile apps, messaging platforms and traditional banking instruments — a combination that complicates detection but leaves a digital trail authorities can follow if properly preserved and examined.
