Local Police
Roughly fifty automobiles have been marked with what appears to be human blood in the German municipality of Hanau near Frankfurt, according to authorities.
Cars, building surfaces and postal boxes were marked, in some cases with Nazi symbols, they stated in a release.
Officers state they were contacted in the late hours on Wednesday evening, when a man observed that a automobile in the Lamboy area of Hanau had been marked with a reddish liquid.
The fluid had been applied in the pattern of a Nazi symbol, they reported.
Police then located multiple other marked automobiles and house walls in the nearby vicinity.
Nazi symbols are illegal in Germany under laws banning the public exhibition of Nazi symbols.
Officials say early analysis show the liquid was likely blood from a person.
"There is still no clue as to its origin; investigators are not yet cognizant of any harm in relation with the event," they added.
Municipal representatives said they were working "to unravel the mystery" and have appealed to the public for details.
A high-ranking official said the vandalism made him without words and required to be resolved quickly.
"This event strikes at the core of Hanau and revives the pain of the extremist violent incident five years ago," he wrote on online, recalling the death of nine individuals by a gunman focusing on residents of foreign heritage in five years prior.
