Kolkata: A Bidhannagar Police detective department team busted an illegal SIM box operation, which routed international calls into Indian networks by masking them as domestic traffic, in an upscale housing complex in Hatiara. Cops arrested one person, Abir Sk alias Monirul Islam Sajib, suspected to be a Bangladeshi national though he claimed to have Indian ID papers.Even at the time cops entered the fifth-floor flat at Galaxy Apartment, police said, the setup was being used to convert international VoIP calls into local ones, dodging International Gateway Exchanges and checks. A lot of traffic was picked up ahead of the Bangladesh polls, said police. The devices seized formed a system that could handle a large volume of calls, said Bidhannagar CP Murlidhar Sharma. tnn
