History

Historical Context

The 22 October 2015 sword attack at Trollhättan’s Kronan Primary School, carried out by 21-year-old Anton Lundin Pettersson, killed three and wounded two, prompting Prime Minister Stefan Löfven’s visit and tighter school security. On 21 August 2026 a similar sword assault at Brinellskolan in Västmanland left one dead and three injured, reviving debate over weapon bans and online radicalisation.
