Sweden has seen some high-profile attacks at educational institutions.In February 2025, a 35-year-old man killed 10 people at an adult education centre in Orebro - Sweden's worst mass shooting. Police said it was motivated by the killer's wish to end his life because of financial and psychological woes. In March 2022, an 18-year-old student fatally stabbed two teachers at a secondary school in the southern city of Malmo. In 2015, two teachers and a pupil were stabbed to death in a school in the western town of Trollhattan by a masked man with a sword and a large knife.The 21-year-old perpetrator, who posed with students before starting his killing spree, was shot dead by police. The attack, which then-Prime Minister Stefan Löfvenplace called a 'black day for Sweden', was racially motivated, authorities said.The attacker picked his victims by their skin colour, according to video evidence seen by police at the time.'He chose dark skinned people, not white. We are convinced it was a hate crime with a racist perspective,' said Niclas Hallgren, the chief of police in Trollhättan.'He was dressed in a way that suggested a racist background [and] video at the scene showed he acted in a military fashion. His actions and the way he looked draws the mind to the Nazis,' Hallgren told journalists.
