Student killed and others injured in school sword attack in Sweden

On Friday, August 21, 2026, an 18-year-old former student launched a violent attack with a sword at the Brinellskolan high school in Fagersta, central Sweden. The incident, which occurred at an institution serving approximately 450 students aged 16 to 20, resulted in the death of a 17-year-old girl and left two other teenagers seriously injured. Police arrived at the scene, successfully neutralized the threat, and took the perpetrator into custody.

Authorities are currently investigating the suspect's motives and potential ties to online communities that promote school violence. A TikTok account believed to be linked to the suspect posted a photograph of a sword taken inside the school shortly before the attack; the account also contained references to previous mass violence incidents, including the 2015 Trollhattan school attack and the Norwegian extremist Anders Behring Breivik. While initial reports regarding the police response varied, including conflicting claims about whether the suspect was shot, it is confirmed that the individual was detained and there is no ongoing threat to public safety. Local authorities have imposed security measures at other schools and public buildings in the town of approximately 12,000 residents as the investigation continues.
