Around 50 cars have been smeared with what appears to be human blood in the German town of Hanau in proximity to Frankfurt, according to authorities.
Vehicles, building surfaces and mailboxes were defaced, in some cases with prohibited symbols, they reported in a official communication.
Officers say they were contacted in the late hours on Wednesday, when a man noticed that a vehicle in the Lamboy area of Hanau had been covered with a reddish liquid.
The liquid had been drawn in the form of a swastika, they added.
Police then found numerous other vandalized automobiles and residential walls in the nearby vicinity.
Nazi symbols are prohibited in Germany under laws outlawing the visible presentation of Nazi-era symbols.
Law enforcement say early analysis indicate the substance was probably human blood.
"Currently there is no clue as to its source; authorities are presently not aware of any harm in association with the incident," they commented.
Municipal representatives stated they were trying "to resolve the mystery" and have asked to the residents for information.
A high-ranking representative said the attack made him speechless and had to be addressed quickly.
"This act strikes at the core of Hanau and reopens the pain of the far-right terrorist attack half a decade ago," he stated on social media, mentioning the death of nine individuals by a gunman aiming at people of foreign heritage in five years prior.
