LUCKNOW, Aug. 31 -- An Army officer and a police constable were duped of thousands of rupees by scammers posing as service representatives, in two separate cases of cyber fraud. Both victims have lodged complaints on the cybercrime portal on Friday, and investigations are underway, said police. In the first case, Lieutenant Colonel Bijith KPS, posted at AMC Centre and College, fell victim to a scam while updating the SBI YONO mobile app. According to his complaint, after downloading the app from the bank branch, his phone began heating up. Shortly after, he received a WhatsApp call from an unidentified number. The caller, claiming to be a Samsung customer care executive, said the officer had downloaded the wrong application and guided him through a series of steps, leading to a loss of Rs.50,000. Realising the fraud, the officer filed a complaint with the cyber cell. In another incident, head constable Gyanendra Singh, deployed at Gate No. 8 of the Vidhan Sabha for security, lost Rs.94,000 while trying to return a defective neckband purchased from Flipkart. He contacted a customer care number found on Google, where the fraudster sent him a link and asked him to install an app and enter his details. Soon after, the money was debited from his account. An FIR has been registered based on the mobile number used in the scam. "We are investigating the matter," said Hazratganj SHO Vikram Singh....
