German police say Chinese men employed Telegram to circulate videos of sexual assault and details for drugging victims.
The platform enabled private groups to exchange prohibited content.
The investigation led in the detention of a Chinese doctor charged of operating a “driving school” that exploited women for rape.
Authorities state the doctor coordinated the ring using Telegram chat rooms.
A separate report confirms that Telegram groups have been leveraged by offenders to spread similar material across Germany.
The case highlights law‑enforcement focus on encrypted messaging apps.
