A Swedish court on Friday convicted a 20-year-old man of participation in a terrorist organization for his involvement in neo-Nazi group Maniac Murder Cult (MKY), sentencing him to 1.5 years in prison.

The Attunda District Court said in a statement that the man, Swedish citizen Emil Erdin, was involved in building up a Swedish branch of the right-wing extremist organization between November 2025 and February 2026, when he was arrested.

"The District Court has ruled that MKY is a terrorist organization, and the 20-year-old man has now been convicted for his involvement in it," the court said in the statement.

Erdin has admitted liability for membership of a terrorist organization, his defence lawyer said on Friday before the verdict.

The lawyer told Reuters her client had not yet decided whether to appeal against the verdict.
