The Mumbai Police Crime Branch, investigating the illegal telephone exchange racket in which international calls were allegedly being made to India at local rates, has claimed that a Bangladeshi man operating out of Saudi Arabia was the mastermind of the racket, Indian Express newspaper reported. The person identified currently as ‘Mohan' was the one who had enabled the five arrested accused in India to carry out the racket. The five were produced before a local court Monday and remanded in police custody until August 18. Last week, the Mumbai Police busted a racket where incoming calls were made to India from Middle Eastern countries, especially Saudi Arabia. The Voice over Internet Protocol (VoIP) calls were, however, made bypassing the country's international calling gateways, meaning the calls would not be detected by the Department of Telecommunications (DoT).
