Area Police
Approximately 50 automobiles have been covered with what seems to be human blood in the German municipality of Hanau close to Frankfurt, according to authorities.
Vehicles, walls and mailboxes were defaced, in some cases with Nazi symbols, they reported in a release.
Law enforcement say they were notified in the late hours on Wednesday evening, when a individual noticed that a vehicle in the Lamboy area of Hanau had been marked with a reddish-hued liquid.
The substance had been placed in the form of a swastika, they stated.
Law enforcement then found many other smeared automobiles and house walls in the adjacent neighborhood.
These symbols are illegal in Germany under legislation prohibiting the public exhibition of Nazi symbols.
Law enforcement say initial examinations indicate the liquid was most likely human bodily fluid.
"At present there remains no clue as to where it came from; officials are currently not informed of any harm in association with the event," they added.
City officials announced they were trying "to resolve the case" and have appealed to the residents for tips.
An important political figure said the attack left him stunned and had to be solved quickly.
"This event strikes at the core of Hanau and reopens the trauma of the far-right attack half a decade ago," he posted on online, mentioning the killing of nine individuals by a gunman targeting individuals of immigrant origin in five years prior.
