NAVI MUMBAI, May 31 -- The central crime unit of Navi Mumbai police has busted an international gang of cybercriminals who defrauded people by placing them under 'digital arrest' and falsely accusing them of breaking the law. Three members of the gang were arrested after a 59-year-old doctor and medical college professor was duped of Rs.1.82 crore, said police. The doctor and medical college professor was first contacted by the gang via a WhatsApp video call on January 14 this year. Gang members claimed they were income tax officers and said the Delhi police had registered a complaint against her as a firm registered in her name had defaulted on taxes worth Rs.8.6 lakh. Subsequently, they sent her letters on forged letterheads of the Criminal Bureau of Investigation, the Enforcement Directorate and the Supreme Court, claiming her credit cards were linked to criminal cases in north India. "The woman was led to believe that she was under digital arrest and was told that all her property would be verified by the RBI (Reserve Bank of India)," said Ajaykumar Landge, assistant commissioner of police (crime). "She was asked to submit details of all her investments and transfer money to the accused, which they said would be refunded once the verification of her property was complete." Between January 14 and February 15, the woman transferred a total of Rs.1.82 crore to six bank accounts based on details provided by the accused. She filed a complaint with the cyber cell on February 17, after realising that she had been duped. Three teams were formed subsequently to conduct a probe, said senior police inspector (crime) Sunil Shinde, the investigating officer in the case. "We undertook technical investigation and traced the bank transactions thoroughly, which led us to the three accused," Shinde said. The first breakthrough came on April 18 when Ramesh Babulal Sheth alias Patwa, 45, a resident of Andheri, and Amish Deepak Tulshidas Shah, 42, a resident of Kalbadevi, were arrested. While they were sent to judicial custody on April 25, the third accused, Ahmedabad resident Rajkumar Gelaram Narang, 55, was arrested on May 23. Narang has been remanded in police custody till May 30. HTC...
