German police say Chinese men leveraged Telegram to share videos of sexual assault and details for drugging victims.
The platform allowed private groups to share prohibited content.
The investigation led in the detention of a Chinese doctor accused of operating a “driving school” that exploited women for rape.
Authorities say the doctor managed the operation using Telegram chat rooms.
A additional report shows that Telegram groups have been used by offenders to spread similar material across Germany.
The case underscores law‑enforcement focus on secure messaging apps.
