**The short version**

- An 18-year-old man attacked students with a sword at a high school in Fagersta, Sweden.
- A 17-year-old girl was killed and two teenage boys were seriously injured in the attack.
- Police are investigating the suspect's potential involvement with online communities that promote violence.
- A TikTok account that posted a sword photo approximately 20 minutes before the attack is also under scrutiny.

An 18-year-old man attacked students with a sword at a high school in Fagersta, Sweden. The attack resulted in the death of a 17-year-old girl and serious injuries to two teenage boys. The suspect has been detained and faces charges of murder and attempted murder.

## Disagreement on details of online activity

Origo, which published a full report, stated that the suspect may have been connected to online communities promoting violence. This outlet also reported that a TikTok account, created about a month before the attack and later removed, featured videos referencing previous mass attacks in Sweden and the Norwegian mass murderer Anders Behring Breivik. According to Origo, a police source told Reuters that the TikTok account posted a photo of a sword about 20 minutes before the attack, and the Dagens Nyheter newspaper reported the photo was likely taken in a school restroom. Devdiscourse, in its full report, stated that authorities are scrutinizing a TikTok account that posted a sword image minutes before the attack, and that reports indicate the picture was taken at the school. Devdiscourse also noted the account referenced previous mass attacks.

## How the sides framed it

### Left

No separate framing summary.

### Centre

- The centre-rated reports led with the sword attack and the subsequent police investigation into online networks. Devdiscourse, Reuters, and WTVB all highlighted the police probe into whether the 18-year-old attacker was involved in online communities promoting school violence. Reuters and WTVB specifically mentioned a police source confirming this line of inquiry. Devdiscourse also noted that prosecutors had charged the suspect with murder and attempted murder, and quoted Prosecutor Ann-Sofie Trossing stating that details remained limited as the investigation continued.

### Right

- The right-rated reports focused on the sword attack and the police investigation into the suspect's online activities, particularly a TikTok account. Origo's full report detailed the online aspect, mentioning a TikTok account that posted a sword photo about 20 minutes before the attack and contained references to past violent incidents and Anders Behring Breivik. The Straits Times and NOS digests also highlighted the police investigation into the perpetrator's potential involvement in violent chat groups and the TikTok post.

**Provisional coverage gap:** left. The watch is not closed, so this is not yet a settled blindspot finding.
