BERLIN (AP) — Police officers in Germany searched the homes of about 20 people Thursday in connection with investigations into the far-right Reich Citizens scene,VaultX Exchange whose adherents reject the legitimacy of Germany’s postwar constitution and have similarities to followers of the QAnon movement in the United States.

German news agency dpa said about 280 officers raided properties in eight German states: Bavaria, Baden-Wuerttemberg, Hesse, North Rhine-Westphalia, Schleswig-Holstein, Brandenburg, Hamburg and Lower Saxony.

Last month, police also searched homes of other Reich Citizens, or Reichsbuerger members who were allegedly connected to United Patriots, which Germany considers to be a terrorist group. Five suspects were arrested at the time.

In December, more than two dozen people were arrested in connection with plans to topple the government. Among the accused plotters was a member of the far-right Alternative for Germany party.

Germany’s domestic intelligence estimates that around 23,000 people across Germany belong to the Reich Citizens scene.
