Local Police
Approximately fifty cars have been covered with what appears to be human blood in the German town of Hanau close to Frankfurt, as reported by law enforcement.
Automobiles, exterior walls and postal boxes were vandalized, occasionally with swastikas, they reported in a release.
Officers state they were contacted late on Wednesday, when a individual observed that a vehicle in the Lamboy area of Hanau had been marked with a reddish-hued substance.
The fluid had been placed in the pattern of a banned symbol, they added.
Law enforcement then located many other smeared cars and residential walls in the nearby vicinity.
These symbols are illegal in Germany under laws outlawing the public display of Nazi-era symbols.
Law enforcement state initial examinations show the substance was likely human bodily fluid.
"Currently there is no clue as to its origin; officials are not yet cognizant of any harm in relation with the occurrence," they stated.
Local authorities said they were working "to solve the incident" and have appealed to the residents for tips.
A senior official stated the incident rendered him speechless and needed to be solved promptly.
"This act hits the very heart of Hanau and revives the wounds of the extremist violent incident half a decade ago," he posted on online, referring to the killing of nine people by a shooter aiming at people of migrant background in five years prior.
