Police arrested four alleged leaders of the banned far-right group, the Kingdom of Germany, including its founder Peter Fitzek.
A spokesman for the prosecutor's office said the German man, between 37 and 59, was detained Tuesday morning as part of a wider crackdown on the extremist imperial citizenship movement.
The spokeswoman said the suspect will appear in a Karlsruhe Federal Court on Tuesday and Wednesday.
According to the spokeswoman, two arrests were conducted in Saxony, Germany, one in Brandenburg and the other in Rhineland-Partnert. In addition, authorities searched the home of a suspect in the state of Solothurn, Switzerland.
German Interior Minister Alexander Dobrindt banned the far-right group “The Kingdom of Germany”, an outstanding faction of the Imperial Citizen Movement.
The so-called imperial citizen or Reichsbürger believed that the modern German Republic illegally replaced the German Empire, which was founded in 1871, and relied on the Nazi regime until 1945. They rejected the legitimacy of the modern federal state of Germany and its laws.
