Three violent attacks at Polish schools occurred this week, resulting in one woman's death and several other injuries. A 37-year-old caretaker was killed after a 15-year-old entered a primary school in Leszczydół-Nowiny, north of Warsaw.
On Wednesday, a 19-year-old student attacked and injured nine people at a vocational school in Mazovian. A woman was arrested on Saturday after she injured three people while attacking a 17-year-old girl at an educational institution in Warsaw.
Police arrested 117 people for threatening to attack schools or fellow students, or for possession of knives and other weapons. Tens of thousands of schools were searched by police following the incidents.
Interior Minister Marcin Kierwiński said a 17-year-old was detained in Sierpc, north-west of Warsaw. The 17-year-old in Sierpc allegedly stated on school grounds that he intended to harm someone and planned to do something dangerous.
Donald Tusk said, "These are very often spontaneous actions inspired by online activity." Tusk added that the country is not dealing with any group organized on a big scale.
The Polish leader claimed the attacks were acts of nihilistic violence associated with the extreme right, noting that some people detained are active in the ultraright environment. Tusk also observed a global and domestic rise in the fascination with violence over recent years and months.
Police noticed a rise in online searches of mass killers who have become idols online and Nazi content. Polish security services convened a special meeting on Sunday after receiving information about a potential attack on Tusk and Wladyslaw Kosiniak-Kamysz.
A special services spokesman described the threat as "deadly serious."
Donald Tusk said, "These are very often spontaneous actions inspired by online activity."
