In a coordinated crackdown, authorities have dismantled a criminal gang that operated across multiple cities, installing hidden cameras in hotels and creating fake videos to sell inferior 'anti-spying' devices. The gang, led by individuals surnamed Lyu, Li, and Zhang, had been selling these devices online under fake names such as 'Liu Yu' and 'Shadow Won't Lie.' The investigation revealed that the gang had been installing the cameras since September 2023, and the information from the devices was inputs into their own database. They would then create fake videos claiming to have discovered the cameras and use these to sell the devices, earning hundreds of millions of yuan in the process. However, the devices were found to be ineffective and possessed no functional features. As of now, 35 people involved in the gang have been taken into custody and are facing various charges.
