STIP, a special education high school on Europalaan in Utrecht, was evacuated on Thursday afternoon due to a telephonic threat. One suspect was arrested, the Telegraaf reports.
Where the threat came from, and what exactly it entailed, is not yet clear. The police are taking it seriously and are investigating the incident.
Police officers in bullet proof vests were present at the school on a large scale. All pupils and teachers were safely evacuated from the school, the STIP director said to the Telegraaf.
