Amok

If there is any indication of dangerous acts of violence on campus (amok, hostage-taking, shooting, terror), a general telephone alarm sounds with a special signal tone and text display "Danger! Stay in the room!"
If there is a direct threat, take cover quickly!
Do not put yourself in danger unnecessarily!
Lock room doors, seek protection behind walls, avoid windows!
Avoid provoking the perpetrator. Intervention is the job of the police.
Wait in cover until the all-clear is given! Only open the door to the police.
If you have your own observations or information about violent acts or perpetrators on campus, please call 110 immediately and inform the police.
