The panic follows two knife attacks on Oct 7 and Oct 8 that left one dead and 11 others injured. A 19 year old wounded 10 people at a school in Ostrołęka on Oct 7, and a 15 year old former student killed a 37 year old female employee at a primary school in Leszczydół-Nowiny the next day. While some schools in the Mazowieckie region canceled classes on Friday, Prime Minister Donald Tusk urged the public to stop spreading unverified claims to prevent copycat crimes.
