Story summary

On October 8, a 15-year-old former student killed one employee and injured two others at a primary school in Leszczydol-Nowiny, northeast of Warsaw, using a sharp object. The incident followed another attack the previous day in Ostroleka where a 19-year-old injured ten people including himself with knives. Both incidents have raised concerns about potential copycat attacks, possibly linked to an internet challenge encouraging violence. Prime Minister Donald Tusk warned of a “grim copycat phenomenon.” In Sierpc, police also detained a 17-year-old suspected of planning an attack and found two knives in his backpack.
