Local Police
Around fifty cars have been marked with what appears to be human blood in the Germany's municipality of Hanau close to Frankfurt, as reported by authorities.
Vehicles, walls and postal boxes were defaced, in some cases with prohibited symbols, they announced in a statement.
Police report they were alerted in the late hours on Wednesday evening, when a man noticed that a automobile in the Lamboy neighborhood of Hanau had been marked with a red-colored fluid.
The substance had been applied in the shape of a banned symbol, they stated.
Police then located multiple other marked vehicles and residential walls in the surrounding area.
Nazi symbols are prohibited in Germany under regulations prohibiting the public exhibition of symbols from the Nazi era.
Law enforcement say preliminary tests show the fluid was likely blood from a person.
"At present there remains no lead as to its source; investigators are presently not aware of any harm in connection with the event," they commented.
Municipal representatives announced they were trying "to resolve the mystery" and have appealed to the residents for information.
A high-ranking political figure commented the attack left him speechless and required to be addressed promptly.
"This event strikes at the core of Hanau and reawakens the wounds of the right-wing violent incident five years ago," he stated on social media, referring to the murder of nine individuals by a gunman aiming at people of migrant background in five years prior.
