DHAKA, Dec. 22 -- Bangladesh's anti-crime elite force Rapid Action Battalion (RAB) Sunday night arrested 39 people, including five from Chinese mainland and 32 from China's Taiwan in capital Dhaka on charge of operating illegal Voice Over Internet Protocol (VoIP), also known as call bypass.

Senior RAB spokesman ATM Habibur Rahman told Xinhua that the RAB personnel, acting on tip-off, recovered VoIP instruments worth about 10 million taka(about 130,000 dollars) from the possession of the arrestees who rented a six-storey building.

"RAB personnel raided the building and arrested two Bangladeshis, five Chinese citizens and 32 Taiwanese men from capital Dhaka's Uttara area Sunday night at 10:00 p.m. (local time) ," he said.

He said the arrestees, who have engaged in illegal VoIP operation for over one and a half year, would be handed over to police.
