Three minutes after the alarm, at 2:09 p.m., several police patrols were on their way to the school. Several schools and preschools in the area are being evacuated.
At 2:16 p.m., the first police patrol on the scene announced that a suspected perpetrator had been neutralized and arrested. According to police, shots were fired during the arrest, but the suspect was not hit.
As police continued to enter the school to secure the premises, a 17-year-old girl was found dead. Three more people were injured.
