Bomb threats, rampages, terror warnings - the scenarios for schools are also changing drastically. It was only on Friday that unknown persons threatened to attack a secondary school. In Linz, two educational institutions are now rehearsing the "threat from within" for the first time. 

What to do if an armed person is in the school? It was only on Friday that the Upper Austrian regional police headquarters received a threatening email. Unknown persons announced that they would attack the Otto-Glökel School in Linz and that "infidels" would die. A large police operation including explosives experts was the result. The investigation into the author of the email is in full swing.
