Authorities are investigating whether the attacks are connected to an online challenge encouraging teenagers to kill as many people as possible. Police said a 37-year-old woman who worked as a caretaker died in the Thursday morning attack at the school in Leszczydol-Nowiny, northeast of Warsaw. The school's head teacher, Krzysztof Ochmanski, was injured while subduing the teenager, officials said. Ochmanski told a radio station he heard a scream and ran into a hallway.

"I mean, I didn't know if it was even real — I still don't know if it's true, actually — because it sounds so unreal, so terrifying, just like something out of a movie: some kind of challenge to kill as many people as possible," she said.
