Noida, Sept. 18 -- An 84-year-old retired official lost Rs.1.70 crore to cyber criminals after being put under "digital arrest" for nearly a week, police said on Wednesday. The fraud, spanning September 9 to 15, came to light when the victim recognised the modus operandi in a news report. Police said the victim, a retired deputy director from the union ministry of commerce, stated in his complaint that he received a call on September 9, alleging that a number registered in his name was linked to illegal activity. Despite denying the charge, he was directed to a man posing as a police officer, who accused him of money laundering and said he would face a CBI team, as per the FIR filed at the cybercrime branch police station. The suspects allegedly threatened him over a video call by showing his Aadhaar card and directed him to travel to Mumbai for a probe. "Due to his elderly age, they let him face the seeming investigation online and placed him under digital arrest," the FIR noted. "In two transactions, the victim transferred Rs.1.30 crore and Rs.40 lakh to the fraudsters as part of the questioning. On September 15, when the suspects demanded an additional Rs.20 lakh, he came across a similar news report about digital arrest and shared his ordeal with his son," said station house officer (cybercrime branch police station) Vinod Kumar. "A case under sections of extortion, cheating, and cheating by personation of the BNS and IT Act was registered against unidentified suspects," the SHO added....
