------------------------------------------------------------------------

Fagersta municipality said an assailant armed with a sword entered Brinellskolan on Friday and wounded several people, and that the suspect had been detained [E2]. Police told wires they received an alarm at 14:06 local time, 12:06 UTC, about suspected deadly violence at a school in Fagersta and sent available resources [E1][E4]. One person at the scene was taken into custody and there was no longer danger to the public, a police spokesperson said [E1][E4].

Region Västmanland’s health director Jonas Cederberg said two people had arrived for treatment and were seriously injured, with a third person on the way whose injuries were not yet classified [E1][E3]. SVT later reported the two seriously injured as boys under 18, in a serious but stable condition, and at least one further person with injuries still unclear [E3]. BBC placed two teenagers as seriously injured and a third person wounded without a confirmed grade [E1].

Eight other schools in the area were locked down; those measures were later lifted [E1]. Prime Minister Ulf Kristersson called it a serious incident and said the motive was not yet known [E1]. Students at Brinellskolan had only just returned after the summer break [E1][E4]. SVT put the school’s roll just under 500 [E1].

Local media reported that police shot the suspect in the leg. Police had not confirmed that at the time Dagens Nyheter and Reuters logged the claim [E4][E5]. SVT, citing unnamed sources, said the detained person was an 18-year-old former pupil with a prior assault conviction; that identification is source-attributed, not a police naming [E3][E5]. A TikTok image of a sword on a school toilet, posted shortly before the alarm, is under investigation according to Swedish papers; it is not itself a police finding [E5].

The attack comes a year after the Örebro school shooting, in which ten people were killed [E4]. That comparison is calendar, not a declared copy. Motive, weapon path onto the site, and any filming of the attack remain unmeasured in the official record [E1][E2].

Friday’s load-bearing facts are the 14:06 alarm, the sword, the detention, two seriously injured boys, and a third casualty still being graded [E1][E2][E3]. Who the suspect is, whether police fired, and what the TikTok account proves sit outside the police statement [E4][E5].
