A Tax Authority building on Kloosterweg in Heerlen was evacuated on Friday morning after the discovery of a package containing a powder substance, the Limburg police said on Twitter.
The police are currently investigating what substance the package contained. The building was evacuated as a precaution.
A dispatcher sent firefighter equipment, and requested police assistance at the scene just before 9:30 a.m. The situation was escalated to a GRIP 1 at 10:10 a.m. That means that a commanding officer from one of the emergency services takes command of the entire scene.
