Background and Timeline

Since September 2025, the Intelligence Fusion and Strategic Operations (IFSO) Unit of the Delhi Police Special Cell has been investigating a surge in “digital arrest” scams across India. The breakthrough came in January 2026, when the police dismantled a sophisticated international syndicate using SIMBOX technology to route scam calls from abroad, primarily Cambodia, into India. The operation culminated in the arrest of seven individuals, including a Taiwanese national, and the seizure of 22 SIMBOX devices and over 20,000 SIM cards.

Modus Operandi

The syndicate’s hallmark was its use of advanced telecom manipulation. Fraudsters impersonated Anti-Terrorist Squad (ATS) officers, accusing victims of links to terror attacks such as the Pahalgam and Delhi blasts. Victims were threatened with immediate arrest and placed under “digital arrest”—a psychological tactic involving continuous video or audio surveillance and coercion to transfer funds for “verification.” The SIMBOX devices enabled the syndicate to mask international calls as local Indian numbers, using low-frequency 2G networks and rotating IMEI numbers to evade detection. The operation was coordinated via encrypted Telegram channels, with technical support and hardware supplied by Chinese and Taiwanese nationals, and funding and operational guidance from a Pakistani handler. Nepal served as the current command-and-control hub.

Victim Impact and Financial Losses

Thousands of victims across India were duped, with the total fraud estimated at nearly ₹100 crore. The psychological manipulation inflicted severe emotional distress, with victims coerced into transferring large sums to multiple bank accounts. The syndicate’s infrastructure allowed the same number to appear active in multiple cities simultaneously, further complicating law enforcement efforts.

Investigation and Agencies Involved

The IFSO Unit, with analytical support from I4C and the Department of Telecommunications, conducted a month-long covert surveillance operation, tracing the first SIMBOX installation to Goyla Dairy, Delhi. Raids across Delhi, Punjab, Tamil Nadu, and Mumbai led to the arrest of local operators and the Taiwanese technical mastermind, I-Tsung Chen. The investigation revealed links to a Taiwan-based organized crime network led by Shang-Min Wu, with prior experience in Cambodia’s scam centers. The syndicate’s use of Pakistani-origin IMEI numbers and cryptocurrency laundering raised serious national security concerns. The case is ongoing, with further arrests and asset seizures expected.

Arrests and Legal Provisions

Seven individuals have been arrested, including Indian facilitators and foreign nationals. The case has been registered under sections of the BNS, IT Act, and PMLA, with charges including organized crime, cheating by personation, and money laundering. The operation has been lauded as a rare victory against a transnational cybercrime syndicate.

Broader Implications and Trends

This case exemplifies the convergence of telecom fraud, psychological manipulation, and transnational organized crime. The use of SIMBOX technology and international command structures reflects a new level of sophistication in cyber-enabled extortion. The case has prompted public advisories from I4C, urging citizens to be wary of calls claiming “digital arrest” and to report such incidents via the national cybercrime helpline 1930 or the cybercrime.gov.in portal.
