Area Law Enforcement
Around fifty automobiles have been marked with what seems to be human blood in the Germany's city of Hanau near Frankfurt, as reported by authorities.
Automobiles, walls and postal boxes were marked, in some cases with swastikas, they stated in a release.
Law enforcement report they were contacted in the late hours on Wednesday, when a resident discovered that a car in the Lamboy area of Hanau had been covered with a reddish-hued liquid.
The substance had been placed in the form of a banned symbol, they added.
Officers then found multiple other vandalized vehicles and house walls in the adjacent neighborhood.
Nazi symbols are illegal in Germany under legislation prohibiting the visible presentation of symbols from the Nazi era.
Law enforcement state preliminary tests suggest the substance was probably human blood.
"At present there remains no clue as to where it came from; investigators are not yet cognizant of any physical harm in association with the incident," they stated.
Local authorities announced they were trying "to resolve the mystery" and have asked to the residents for details.
An important official said the attack left him stunned and needed to be solved rapidly.
"This incident strikes at the core of Hanau and revives the pain of the extremist violent incident half a decade ago," he stated on a platform, referring to the murder of nine people by a shooter targeting individuals of foreign heritage in five years prior.
