Second Suspect Arrested in Swedish School Sword Attack

A second suspect has been arrested in connection with the deadly Swedish school sword attack that killed a 17-year-old girl and wounded three teenagers at Brinell School in Fagersta, central Sweden, on Friday, August 21, 2026. Swedish prosecutors confirmed the man was detained over the weekend during a police operation in the Stockholm area and is now suspected of complicity in murder and attempted murder. The development marks a significant turn in the investigation, as police had initially said there was no reason to believe multiple perpetrators were involved.

What happened in the Fagersta sword attack?

The attack unfolded Friday afternoon at Brinellskolan, a high school in Fagersta, about 150 km northwest of Stockholm. An 18-year-old former student, Liam Nebel, entered the school wearing a helmet and dark clothes, armed with a sword. A 17-year-old girl was killed, and three boys were injured; two of them, aged 12 and 17, remained in serious condition in hospital, while a third was later discharged.

Nebel was subdued by police during his arrest and remains in custody. He was charged with murder and attempted murder on Sunday, according to Swedish media. Police said they had fired shots during the arrest.

Who is the second suspect in the Swedish school sword attack?

The newly arrested man was detained over the weekend in a police raid in the Stockholm area, according to Aftonbladet, which cited sources inside the investigation. The prosecutor's office said he is suspected of complicity in murder and attempted murder, though his age and alleged role have not been disclosed. A decision on whether he will remain in pre-trial detention or be released is expected by Wednesday, August 27.

He is suspected of complicity in murder and attempted murder, the Swedish prosecutor's statement said. Investigators have not yet explained how the suspect allegedly helped Nebel.

True Crime Community and online radicalization

Swedish media, including Dagens Nyheter and SVT, reported that Nebel was highly active in the True Crime Community on TikTok, an international online subculture that glorifies extreme violence, mass murderers, and weapons. Police have confirmed they are investigating whether Nebel participated in chat groups that promote school violence.

An SVT investigation found that a TikTok account linked to the suspect had 3,700 followers, more than half a million views, and 17 AI-animated edits of dancing perpetrators before it was removed. The account posted a picture of a sword 25 minutes before police were alerted to the attack. The True Crime Community has been linked to other violent incidents in Europe, raising alarm among security researchers.

A violent past and a chilling final message

Nebel had a history of violence. He was previously convicted of assault after punching another student in the stomach and attempting to strangle him last year. Classmates described him as a boy with mood swings. Shortly before the attack, he reportedly sent his former foster family a message reading thanks for everything.

Investigators believe Nebel was inspired by Anton Lundin Pettersson, who killed three people with a sword at a school in Trollhättan, Sweden, in October 2015 and deliberately targeted victims of foreign origin. The 2015 Trollhättan attack was racially motivated and influenced a generation of online extremists, including Nebel, according to investigators.

How is Sweden responding to the Fagersta attack?

Prime Minister Ulf Kristersson visited Fagersta for a memorial, saying: What must never happen has happened again. A minute of silence is planned in Fagersta on Friday afternoon to remember the victims. The attack has renewed debate about school violence prevention in Sweden and the role of social media in radicalizing young people. The Swedish government has pledged to review school safety measures and the role of social media platforms in spreading violent content.

Sweden has experienced several deadly school attacks in recent years, including the 2025 Örebro mass shooting, which was the country's worst mass shooting. Experts say the True Crime Community's glorification of violence is a growing concern for law enforcement across Europe.
