Approximately fifty vehicles have been marked with what seems to be blood from a person in the Germany's town of Hanau near Frankfurt, police confirm police.
Automobiles, walls and mailboxes were defaced, in some cases with swastikas, they announced in a release.
Officers say they were notified late on Wednesday evening, when a individual discovered that a car in the Lamboy neighborhood of Hanau had been covered with a reddish liquid.
The substance had been applied in the shape of a Nazi symbol, they added.
Police then found many other vandalized vehicles and house walls in the nearby vicinity.
Nazi symbols are illegal in Germany under legislation banning the public exhibition of symbols from the Nazi era.
Police say initial examinations indicate the fluid was probably blood from a person.
"There is still no clue as to where it came from; authorities are currently not cognizant of any physical harm in connection with the occurrence," they added.
City officials said they were working "to unravel the case" and have appealed to the community for details.
A senior official stated the attack left him speechless and required to be addressed quickly.
"This event affects the core of Hanau and reopens the pain of the right-wing terrorist attack five years ago," he wrote on social media, recalling the death of nine individuals by a gunman targeting people of foreign heritage in five years prior.
