A disgruntled man attacked personnel and visitors at a municipality building with a spray system filled with ammonia. Most people experienced mild effects from the vapors but two were directly hit and experienced severe effects, losing consciousness. The building was evacuated and first responders were called to assist victims at the collection points and provide instructions. Witnesses reported the ammonia smell and could describe the suspect. Multiple security cameras inside and outside the building captured footage of the incident.
