Two people are arrested for a major VoIP scam as the Ahmedabad cybercrime division cracks a Chinese cyber fraud syndicate.

Two Indian nationals have been arrested by the Ahmedabad City Cyber Crime Branch in a significant crackdown on international cyber fraud. They are allegedly connected to a Chinese cybercrime syndicate that used Voice over Internet Protocol (VoIP) calls that were routed through servers in Thailand, Malaysia, Iran, and Iraq to defraud Indian citizens.

 In response to the tip, a crew stormed a data center in Thaltej, Ahmedabad, which was situated on the eighth floor of Cambay Grand, off the Sarkhej-Gandhinagar Highway.  Three servers owned by Set Square Learning Solution Pvt Ltd were discovered during the operation. These servers were reportedly being used to perpetrate cyber crimes, such as investment fraud and digital arrest, by impersonating representatives of the Telecom Regulatory Authority of India (TRAI).

This complex plan was built up by the defendants, Lavkesh Kumar and Anurag Gupta, who bought 500 Sessions SIP connections from Datafirst DC and utilized them to route foreign calls to Indian nationals.  Using Indian numbers, the accused pretended to be TRAI officials and threatened to block the victims' SIM cards in two hours.

 By renting a server in Germany and connecting it to another server housed in the Ahmedabad data center, the accused was able to pass off international calls as domestic ones.  Cindy Wang, a Chinese accomplice who worked for Quick Com and Snow Fly Online in Hong Kong, provided help for this operation.

Lavkesh Kumar, the accused, played a crucial part in the operation.  He set up the servers and SIP connections in Ahmedabad and founded Set Square Learning Solution Pvt Ltd.  Lavkesh, who has studied up to Standard 10, also has a prior case of visa fraud recorded at Sector-31-32 Police Station in Karnal, Haryana, for which he is out on bail since August 2023.

 The technical configuration of the servers and the international call routing were managed by Anurag Gupta, who has eighteen years of experience in the call center sector.  In addition to being released on bail from a different cybercrime case filed in Sonipat since March 2023, he was previously incarcerated in Haryana, where he met Lavkesh.  Both defendants have longstanding connections to these fraudulent schemes.

These SIP lines were used to make an average of 65,000 calls every day throughout India between April 20 and 24, 2025. The victims were shown Indian numbers using Vodafone-Idea's SIP trunk.  There have been 23 complaints from neighboring states and more than 45 complaints filed in Gujarat alone thus far.

 In order to uncover the entire scope of this global cyber fraud network, the Ahmedabad Cyber Crime Branch has filed a complaint under several provisions of the Indian Penal Code, the IT Act, and the Indian Telegraph Act. Investigations are still ongoing.

 To find further members of this syndicate and fully dismantle their fraudulent activities, more investigations are being conducted.
