Several injured in sword attack at Swedish high school in Fagersta

One person died and three were wounded after a sword-wielding attacker entered Brinellskolan, a high school in Fagersta, central Sweden, on Friday, August 21, prompting a police response and the arrest of the suspect. Local police chief Tommy Alriksson confirmed that one individual was found dead after police entered the school, having shot and arrested the assailant. The arrested suspect, an 18-year-old man, was described by Alriksson as the sole perpetrator, with no indication of multiple attackers. Two individuals were seriously wounded, and a third suffered lighter injuries, according to the police chief.

Regional healthcare director Jonas Cederberg previously reported two teenagers as "seriously wounded," with one undergoing emergency surgery and both in stable condition. The Fagersta municipality stated an assailant armed with a sword had entered the school, leading to lockdowns at Brinellskolan and nearby institutions. Students, just back from summer break, remained in lockdown for over three hours before being released. A crisis center was established in a local sports hall, and emergency services, including ambulances and a helicopter, were deployed to the scene.

The suspect, who had a prior assault conviction and wore a helmet during the attack, drew comparisons to the 2015 Trollhättan school attack, where a sword-wielding assailant killed three people. Swedish broadcaster SVT reported the attacker’s attire resembled that of the 2015 incident, including a helmet and black clothing. A TikTok account allegedly linked to the suspect was investigated by police before being taken down, with posts referencing school attacks and a final image of a sword.

A 16-year-old student, Nellie Strandberg, described witnessing the attacker, who was "bloody all down his back," as she approached the school library. Teachers reportedly avoided answering questions about the incident. The school, which serves 450 students, had previously faced security concerns in May, when students were sent home following a threat. Swedish Prime Minister Ulf Kristersson called the event a "serious incident," emphasizing police efforts to address the crisis. Opposition leader Magdalena Andersson expressed solidarity, stating, "All of Sweden stands with Fagersta in this difficult time."

Authorities continue to investigate the suspect’s motives and the exact circumstances of the attack. The school, located in a town of about 12,000 residents, remains under scrutiny amid Sweden’s history of violence in educational settings. In February 2025, a man killed 10 people at an adult education center in Örebro, and in March 2022, an 18-year-old student stabbed two teachers at a school in Malmö. No direct link to the Fagersta incident has been established, though investigators are examining potential connections.
