Teen wearing helmet camera kills worker at Polish school amid fears of copycat attacks
A 15-year-old boy attacked a Polish primary school he previously attended, killing one employee and injuring two others. The attack occurred on Thursday morning in Leszczydol-Nowiny, northeast of Warsaw. The head teacher subdued the teenager, sustaining injuries himself. This incident follows another school stabbing the previous day in Ostroleka, where a 19-year-old wounded 10 people. Authorities are investigating a potential connection to an online challenge encouraging violence and are concerned about copycat attacks. Prime Minister Donald Tusk ordered increased police presence at schools.
