Rourkela: A Mumbai banker was arrested by Rourkela cyber police allegedly for duping a local of around Rs 6 lakh through a fake traffic e-challan, sent on an instant messaging platform, superintendent of police (SP) Nitesh Wadhwani said on Friday.At a press meet held at the district police headquarters, Rourkela SP Wadhwani said accused Chetan Sharad Kurhade (35), a resident of Parel under Kalachowki police station, was arrested earlier this week in Mumbai and brought to Rourkela on a seven-day transit remand. The cyber police have also seized an iPhone 15, used in the crime, another mobile phone, four credit cards and a PAN card from the accused.On the day, the accused was produced before the subdivisional judicial magistrate, Panposh, who sent him to judicial custody.According to the complaint registered in this connection, the Rourkela resident received a message, which appeared to be an official traffic e-challan notification, on his WhatsApp around 10.30 pm on May 30, asking him to deposit Rs 500 to the Regional Transport Office. After he allegedly clicked the message, he started receiving OTP messages on his phone. He immediately checked his bank balance and discovered that six unauthorised UPI transactions had been executed, with a total unauthorised debit of Rs 5,99,588.53 from his savings account.During the investigation, the transaction trail was examined, and requisitions were issued to the banks, payment intermediaries and other entities concerned for obtaining beneficiary account details, transaction statements, KYC documents and other relevant records. It was revealed that the fraudulent amount had been utilised towards bill payments of credit cards associated with different banks. After obtaining the credit card details and linked mobile phone numbers, a police team was deputed to Mumbai, resulting in the nabbing of accused Kurhade.The seized bank account details were subsequently verified through Samanvaya Portal. The bank account and credit cards linked to the accused were associated with cybercrime complaints from various places, including Haryana, Mumbai, Delhi and Kolkata, involving approximately 18.7 lakh in fraudulent transactions.Further investigation is underway to identify others involved in the cybercrime racket and trace the flow of suspected cyberfraud proceeds.
