- A 15-year-old returned to his former primary school in Leszczydol‑Nowiny on Thursday and stabbed three adults, killing a 37‑year‑old custodian while two other adults were hospitalized.
- Witnesses reported the 15-year-old wore a helmet with a camera that may have been used to film the attack, though investigators have not confirmed whether footage exists.
