"We learned he planned to attend a lecture at the Faculty of Arts building on Celetna Street at 2 p.m., so we immediately responded and evacuated the building, completing the evacuation at 2:22 p.m., and conducting further search operations for this man," Vondrášek said. "At 2:59 p.m. we received the first reports of a shooting at the Faculty of Arts building on Palach Square."
