Overview
- The school leadership shut the Röttgersbach primary school for the day after receiving a threat by email and informed parents early in the morning.
- Duisburg police said the message announced crimes targeting pupils and school employees.
- Officers were sent to the campus, and the criminal police opened an inquiry in close contact with the head teacher.
- Investigators judged the warning unlikely to be carried out, yet the search for the author is ongoing.
- Similar anonymous threats in spring 2025 forced about 20 Duisburg schools into one day of remote learning, and police later named four teenage suspects, including a 15-year-old from Berlin.
