Swedish police said on Friday that one person had died and three had been wounded after a sword-wielding attacker entered a high school in the town of Fagersta in central Sweden.

Local police chief Tommy Alriksson told journalists that one person had been found dead after police entered the school, having shot and arrested the assailant.

Alriksson added that as well as the deceased, three people had been wounded, two of them seriously.

Earlier Friday, the healthcare authority said two boys, both aged between 12 and 17, were being treated in hospital.

"An assailant armed with a sword has entered Brinellskolan and wounded several people," the Fagersta municipality said in an earlier statement, adding the assailant had been detained by police.

Aftonbladet newspaper reported that a person wielding a machete had been shot in the leg by police.

Public broadcaster SVT said ambulances, police cars as well as a police helicopter were outside the school in the small city of about 12,000 inhabitants.

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.
