Poland has deployed more than 20,000 police officers to schools following three stabbing attacks in four days.
One attack killed a school caretaker and injured two teachers.
The nationwide security operation began Monday as Prime Minister Donald Tusk warned of a disturbing rise in youth violence.
Police said they had inspected 80,000 educational institutions and detained 135 people since Friday. But what is driving this alarming trend?
Authorities have dismissed rumours that the attacks were connected to an online challenge or organised group.
However, Tusk warned that internet content glorifying violence could be influencing young people.
This is alongside Nazi ideology, violent video games and what he called a “cult of strength”.
The latest incident occurred Saturday at a further education college in Warsaw, where three people were injured.
Online Warning Signs
Earlier, a 19-year-old wounded 10 people at a school in Ostroleka, while a 15-year-old former pupil allegedly killed a caretaker in Leszczydol-Nowiny.
In another case, police discovered that a boy had recreated his school in the Roblox gaming platform and simulated attacks.
He was also found with a firearm, ammunition and knives.

Interior Minister Marcin Kierwinski delivered a firm warning: “There will be no tolerance for any attacks on Polish children.”
With police now patrolling schools, the challenge extends beyond security.
How can authorities protect students while addressing the online influences and warning signs that may precede real-world violence?
