The indictment was filed at Attunda District Court, and the investigation was conducted by Säpo, according to a press release.
"For the first time, charges are being brought for participation in a terrorist organization regarding the neo-Nazi organization MKY, also known as the Maniac Murder Cult, which can be linked to several serious acts of violence, including murder," said District Attorney Lars Hedvall in a statement.
The crime is alleged to have been committed from November 2025 until the person's arrest in February 2026.
"The actions in the case have included, among other things, the establishment of a Swedish MKY cell, recruitment, and dissemination of propaganda material on behalf of MKY," Hedvall said.
