The Central Crime Branch (CCB) officials stepped up investigations to crack down another illegal telephone exchange operating in the city.
The investigation was taken up based on a complaint filed by Hind Gaurav from the Department of Telecommunications, Ministry of Communications, who found that four SIM cards were being used as SIP/Trunk exchange to convert international calls to local calls.
This, according to Mr. Gaurav, is not only posing a threat to national security, but violates telecommunications rules and is causing huge loss to the State exchequer.
