A 15-year-old former pupil is arrested after stabbing a caretaker at a primary school near Warsaw, killing one person and injuring two others, Polish police said. The attack takes place at the John-Paul II primary school in Leszczydol-Nowiny at about 9am local time, according to multiple reports.

The incident follows another school attack in Poland the previous day, when a 19-year-old wounded multiple people, including himself, at a different school. Several outlets describe police as saying teachers and the head of the school overpower the attacker after the initial assault. Reports also mention authorities detaining the teenager and, in other cases, acting on prior threats connected to potential copycat behavior. Some coverage cites the attacker wearing a helmet-mounted camera and possible links to an online challenge, though details vary by outlet. Police and regional officials describe the victims, including a 37-year-old woman caretaker who dies from her injuries.
