The Daejeon Yuseong Police Department has cracked down on an investment fraud ring that impersonated a famous stock expert and stole over 1.5 billion won in cash and gold bars. The organization used fake stock trading apps, forged employee IDs, and false investment certificates to deceive victims. Police used AI technology to create fake gold bar photos and deliver them to the mastermind, leading to the arrest of the domestic fund manager. This case recovered 258 million won in damages, and investigations are underway to track down overseas-based masterminds. Police warned that there is a high possibility of fraud when stock investment projects send links to induce app installation or show profit verification screens in group chat rooms.
