After receiving two reports of a person possibly armed with a firearm, the police escalated the situation with multiple (specialist) units. Shortly after, it was escalated to Grip 1, allowing various emergency services to cooperate on-site. Due to the size of the buildings and their connections, it took some time to get a complete picture. In the meantime, the university closed the buildings in the area of Princetonlaan-Budapestlaan-Leuvenlaan-Sorbonnelaan earlier. People inside were asked to exit the buildings calmly.
By around 6:00 PM, it became clear that no suspect was found, and there were no concrete signs of threat from the on-site investigation. Thus, the situation was under control, and the police scaled down their response. We are monitoring the situation around the university buildings and conducting further investigations into the reports.
