Local Police
Around 50 cars have been covered with what appears to be blood from a person in the Germany's city of Hanau close to Frankfurt, according to law enforcement.
Vehicles, walls and postal boxes were defaced, sometimes with prohibited symbols, they reported in a statement.
Officers say they were notified in the late hours on Wednesday, when a man noticed that a car in the Lamboy neighborhood of Hanau had been smeared with a reddish liquid.
The substance had been applied in the shape of a banned symbol, they stated.
Law enforcement then located multiple other vandalized cars and house walls in the surrounding area.
These symbols are prohibited in Germany under laws prohibiting the public display of Nazi symbols.
Police state preliminary tests suggest the fluid was most likely blood from a person.
"At present there remains no clue as to where it came from; officials are presently not informed of any physical harm in relation with the incident," they added.
Municipal representatives stated they were working "to resolve the incident" and have appealed to the community for details.
A high-ranking representative said the incident left him speechless and had to be solved quickly.
"This act strikes at the core of Hanau and reopens the wounds of the right-wing attack half a decade ago," he posted on social media, recalling the killing of nine victims by a assailant focusing on residents of immigrant origin in five years prior.
