Local Police
Roughly 50 vehicles have been marked with what appears to be blood from a person in the Germany's municipality of Hanau in proximity to Frankfurt, according to authorities.
Cars, building surfaces and mailboxes were marked, in some cases with prohibited symbols, they reported in a statement.
Law enforcement report they were notified in the late hours on Wednesday night, when a man noticed that a car in the Lamboy neighborhood of Hanau had been marked with a reddish-hued substance.
The substance had been applied in the shape of a banned symbol, they stated.
Officers then discovered multiple other marked cars and house walls in the adjacent neighborhood.
Nazi symbols are illegal in Germany under laws outlawing the visible presentation of Nazi symbols.
Police state preliminary tests indicate the substance was likely blood from a person.
"There is still no clue as to its source; investigators are presently not aware of any harm in association with the incident," they commented.
City officials announced they were trying "to solve the mystery" and have asked to the community for information.
An important representative commented the attack left him stunned and needed to be solved promptly.
"This event hits the very heart of Hanau and reopens the wounds of the far-right violent incident half a decade ago," he wrote on social media, referring to the murder of nine victims by a shooter targeting residents of immigrant origin in five years prior.
