The Brandenburg Office for the Protection of the Constitution warns of a movement of right-wing extremists from West Germany to the East German federal states.
"We see a movement of right-wing extremists from the West to East Germany," said the Brandenburg intelligence chief Jörg Müller, the newspapers of the Funke media group on Wednesday.
Neo-Nazis bought cheap real estate in the east of the country, held concerts there or founded new groups.
"We register that leading figures from the right-wing extremist scene from the old federal states, for example from Bavaria and Dortmund, have gone to Brandenburg or Saxony.
In the scene, you see the East as a new 'settlement area',” said Müller.
This is a dangerous trend, because there is often no strong civil society in the sparsely populated areas that could effectively oppose the right-wing extremists.
