Local Police
Approximately fifty cars have been marked with what seems to be human bodily fluid in the Germany's city of Hanau near Frankfurt, as reported by law enforcement.
Vehicles, walls and postboxes were defaced, occasionally with Nazi symbols, they announced in a official communication.
Law enforcement report they were notified in the late hours on Wednesday night, when a man observed that a car in the Lamboy district of Hanau had been marked with a reddish substance.
The substance had been placed in the pattern of a swastika, they added.
Police then discovered numerous other marked vehicles and building exteriors in the adjacent neighborhood.
These symbols are illegal in Germany under laws outlawing the public exhibition of symbols from the Nazi era.
Police say early analysis indicate the substance was probably human blood.
"Currently there is no indication as to its origin; authorities are currently not informed of any harm in connection with the incident," they stated.
Local authorities announced they were attempting "to unravel the mystery" and have requested to the community for information.
An important official stated the attack made him without words and had to be solved promptly.
"This act strikes at the center of Hanau and revives the trauma of the extremist terrorist attack five years ago," he wrote on online, recalling the death of nine people by a assailant targeting people of immigrant origin in five years prior.
