Detailed Profile of Liam Nebel: Suspect in Fagersta School Attack

Liam Nebel, 18, has been detained on suspicion of murder and attempted murder following the deadly attack at Brinellskolan in Fagersta, where a 17-year-old girl was killed and three boys injured, two seriously. Nebel, a student at the school with valid access through an ID card, did not oppose his detention but denied the charges of attempted murder, according to his defense attorney Anes Sabic.

Nebel's background reveals a troubled upbringing marked by neglect, which led to his placement in youth care under the LVU law last year. Court records show he was convicted in 2025 for assaulting another student, reflecting longstanding issues with impulse control and emotional management.

Shortly before the attack, a TikTok account linked to Nebel posted disturbing content, including images of a sword placed on a bathroom floor and videos glorifying past school attackers such as Anton Lundin-Pettersson and the perpetrator of the Trollhättan school attack. This account, created in July, suggests possible premeditation or fascination with such violence. Witnesses described the attacker as dressed in black clothing, wearing a helmet and mask during the assault.

The motive behind the attack remains unclear. The prosecutor must file formal charges or request an extension of Nebel's detention by September 21, 2026.

This detailed profile provides further insight into Nebel's troubled history and the circumstances leading up to the tragic event at Brinellskolan.
