Overview
- A large police deployment sealed the grounds of a Velbert vocational college after reports that a student had threatened classmates.
- Officers followed standard school-safety procedure by keeping pupils in their classrooms rather than evacuating the building.
- Specialized units known as an Einsatz‑Hundertschaft checked the site after initial attempts to contact the suspected student at school failed.
- Police located the student at his registered address and issued an all‑clear around midday with no injuries reported.
- Local reporting names the school the 'Zitronenbunker' and officials say the next steps are an investigation into the credibility of the threats and any potential legal follow-up.
