Swedish national indicted for participation in terror organization

For the first time in Sweden, an individual has been indicted for participation in the neo-Nazi group MKY, commonly referred to as Maniac Murder Cult. The indictment, filed at the Attunda district court in Stockholm's northern suburbs, charges the individual with involvement in a terror organization.

MKY is characterized as a "violence-glorifying right-wing extremist organization" with connections to multiple severe violent acts, including murder. According to prosecutor Lars Hedvall, the charges include the establishment of a Swedish MKY cell, recruitment efforts, and the dissemination of propaganda material on behalf of the organization.

For first time, indictment for participation in terror organization is being issued concerning the neo-Nazi organization MKY, also known as Maniac Murder Cult, and which can be linked to several serious violent incidents, including murder.

The investigation was conducted by the Swedish Security Service (Säkerhetspolisen), Sweden's equivalent of Norway's PST. The alleged criminal activities took place between November 2025 and the individual's arrest in February 2026.

The U.S. Military Academy's Combating Terrorism Center (CTC) reports that MKY was founded in Ukraine and rapidly expanded into Russia, first appearing online around 2018. The group has been linked to numerous attacks in Russia, and the CTC notes that they are "redefining terrorism, recruitment, and mass violence" in the United States.
