Roughly fifty cars have been covered with what seems to be human blood in the Germany's municipality of Hanau in proximity to Frankfurt, according to authorities.
Vehicles, walls and mailboxes were marked, in some cases with prohibited symbols, they announced in a statement.
Law enforcement say they were alerted in the late hours on Wednesday evening, when a man discovered that a automobile in the Lamboy neighborhood of Hanau had been marked with a reddish substance.
The liquid had been placed in the pattern of a Nazi symbol, they reported.
Officers then discovered numerous other marked vehicles and building exteriors in the adjacent neighborhood.
Swastikas are prohibited in Germany under legislation banning the visible presentation of Nazi-era symbols.
Police state initial examinations suggest the liquid was probably blood from a person.
"At present there remains no clue as to where it came from; authorities are currently not aware of any harm in relation with the incident," they added.
City officials announced they were attempting "to resolve the mystery" and have asked to the community for tips.
A high-ranking official commented the attack rendered him stunned and needed to be addressed rapidly.
"This act strikes at the center of Hanau and reawakens the trauma of the extremist attack half a decade ago," he posted on social media, referring to the death of nine people by a shooter aiming at residents of foreign heritage in five years prior.
