Local Police
Roughly 50 automobiles have been marked with what seems to be blood from a person in the Germany's city of Hanau near Frankfurt, police confirm law enforcement.
Automobiles, walls and postboxes were marked, in some cases with Nazi symbols, they reported in a official communication.
Police state they were contacted late on Wednesday evening, when a resident discovered that a automobile in the Lamboy area of Hanau had been marked with a reddish-hued fluid.
The substance had been applied in the pattern of a swastika, they added.
Officers then discovered numerous other smeared cars and residential walls in the nearby vicinity.
Nazi symbols are prohibited in Germany under regulations outlawing the public display of symbols from the Nazi era.
Police say initial examinations indicate the liquid was likely blood from a person.
"Currently there is no clue as to its origin; authorities are presently not cognizant of any injuries in association with the incident," they added.
Local authorities stated they were attempting "to solve the mystery" and have requested to the community for information.
A high-ranking political figure commented the vandalism made him stunned and needed to be resolved quickly.
"This incident hits the very heart of Hanau and reawakens the trauma of the extremist terrorist attack half a decade ago," he posted on online, mentioning the killing of nine individuals by a gunman aiming at individuals of immigrant origin in five years prior.
