Ahmedabad cyber crime branch busts Chinese cyber fraud syndicate; two arrested for massive VoIP scam
Updated: May 24th, 2025
In a major crackdown on international cyber fraud, the Ahmedabad City Cyber Crime Branch has arrested two Indian nationals allegedly linked to a Chinese cyber crime syndicate that defrauded Indian citizens using Voice over Internet Protocol (VoIP) calls routed through servers in countries such as Thailand, Malaysia, Iran, and Iraq.
Acting on the tip-off a team raided a data centre located on the eighth floor of Cambay Grand, off Sarkhej-Gandhinagar Highway in Thaltej, Ahmedabad. The raid uncovered three servers belonging to Set Square Learning Solution Pvt Ltd that were allegedly being used to commit cyber frauds, including digital arrest and investment fraud, by posing as officials from the Telecom Regulatory Authority of India (TRAI).
The accused, Lavkesh Kumar and Anurag Gupta, had set up this elaborate scheme by purchasing 500 Sessions SIP connections from Datafirst DC and routing international calls to Indian citizens. The accused impersonated TRAI officials and threatened to block victims’ SIM cards within two hours, using Indian numbers.
The accused’s modus operandi involved renting a server in Germany and linking it to another server hosted at the Ahmedabad data centre, effectively masking international calls as domestic calls. This operation was supported by a Chinese collaborator, Cindy Wang, working for companies Quick Com and Snow Fly Online in Hong Kong.
The role of the accused Lavkesh Kumar was central to the operation. He formed Set Square Learning Solution Pvt Ltd and arranged for the servers and SIP connections in Ahmedabad. Lavkesh, who has studied up to Standard 10, also has a prior case of visa fraud registered at Sector-31-32 Police Station in Karnal, Haryana, for which he is out on bail since August 2023.
Anurag Gupta,who has been in the call centre industry for 18 years, handled the technical setup of the servers and the routing of international calls. He was previously jailed in Haryana, where he met Lavkesh, and was also out on bail from another cybercrime case registered in Sonipat since March 2023. Both accused have deep-rooted ties to these fraudulent operations.
During the period of 20–24 April 2025, an average of 65,000 calls per day were made across India using these SIP lines, with Vodafone-Idea’s SIP trunk displaying Indian numbers to the victims. So far, over 45 complaints have been registered in Gujarat alone and 23 complaints from other states.
The Ahmedabad Cyber Crime Branch has registered a case under multiple sections of the Indian Penal Code, the IT Act, and the Indian Telegraph Act, and is continuing investigations to unearth the full extent of this international cyber fraud network.
Further investigations are ongoing to identify other members of this syndicate and dismantle their fraudulent operations completely.
