The size of a radical movement that rejects the legitimacy of the modern German state has grown to 19,000. Authorities have stepped up efforts to crack down on the far-right extremists, some of whom are armed.
The number of people known to be active in Germany's Reichsbürger (Reich Citizen) and Selbstverwalter (Sovereign Citizen) movements has almost doubled to 19,000 over the past two years, the Interior Ministry admitted on Friday.
The ministry acknowledges that up to 950 members have been categorized as right-wing extremists.
It was responding to a question in Germany's Bundestag from the Green party about the group's membership and its most radical members.
Reichsbürger describes a loose grouping of people who do not recognize the authority of the current system of government. Members insist that the laws of both the German Empire and Nazi Germany still apply today, and many of them refuse to pay taxes or fines.
Germany's domestic intelligence agency said there were 10,000 Reichsbürger in 2016 and some 16,500 members by last year. The agency believes its focus has helped it uncover additional members.
The NDR/Süddeutsche report broke down how heavily armed members in some German states were. For example, in the state of Brandenburg just 37 Reichsbürger members own some 150 firearms, while in the state of Thuringia 18 members own 79 rifles.
The movement gained significant traction after a member shot dead a policeman in Bavaria in October 2016.
A few months later, a member in the southwestern city of Trier fired a soft-air rifle in a public square and threatened several passers-by.
A return to the bad old days?
Since then, several officers have been injured in police operations against members. The most recent, last month, saw several Reichsbürger clash with police after a protest in Erlenbach in the state of Baden-Württemberg turned violent.
Responding to the latest figures, the Greens interior affairs spokeswoman, Irene Mihalic, expressed concern that the "number of Reich citizens with their state-toppling plans is growing and growing."
Mihalic complained that "the number of weapons permits being withdrawn seems to have stagnated."
