Bengaluru: Two gangs of three members each operating illegal telephone exchanges with a similar modus operandi – converting international calls to local calls – landed in the custody of Central Crime Branch police.
The defendants are Ravichandra, Subair, Manu MM, Ismail Abdulla, Jouhar Shareef and Shahir. Except for Ravichandra, the other five are from Kerala. All resided at Mahadevapura and Chikkasandra near Hesaraghatta.
Officials recovered 17 SIM box devices, two Session Initiation Protocol (SIP) trunk call devices, nine Primary Rate Interface (PRI) devices, five laptop computers, two desktop computers, nine mobile phones, six routers and 205 gang SIM cards.
Manu, a software engineer, helped the gang set up a telephone exchange and took care of the technical aspects. They illegally converted international calls to local calls using Voice Over Internet Protocol (VOIP), police said. The telephone exchanges were at Mahadevapura and Chikkasandra.
“CCB Police will investigate how and from whom the suspects obtained pre-activated SIM cards en masse. Officials will also review the procedures followed by the communications service provider when providing SIP line calling devices,” Police Commissioner CH Pratap Reddy said.
The cybercrime police registered two cases based on complaints filed by officials of the telecommunications department of the Ministry of Communications. Satyanarayana N filed a lawsuit on May 18, alleging that some disbelievers have run an illegal telephone exchange in the city for the past three months. Another officer, KN Subba Reddy, filed a second complaint on May 25. CCB police raided five locations and arrested the gang.
