In the small town of Kölleda in Thuringia, two swastikas were discovered on Monday.
Unknown people had sprayed the National Socialist symbols with blue paint on a house facade in Herrengasse, as the police announced on Tuesday.
Erfurt / Berlin - It is the twentieth incident of this kind in Kölleda since the end of September that was reported to the police.
It is assumed that the acts are related to each other, as a similar color was used and a similar environment was selected, as a spokeswoman for the Thuringia police said.
The symbols were therefore mainly sprayed on the walls in the city center of the 6,300-inhabitant municipality in the evening.
The police are asking residents for clues.
