Approximately fifty cars have been marked with what appears to be human blood in the Germany's municipality of Hanau near Frankfurt, according to police.
Automobiles, building surfaces and mailboxes were vandalized, in some cases with Nazi symbols, they reported in a statement.
Police state they were notified in the late hours on Wednesday night, when a resident observed that a car in the Lamboy neighborhood of Hanau had been marked with a red-colored fluid.
The fluid had been drawn in the shape of a swastika, they added.
Law enforcement then discovered multiple other vandalized automobiles and residential walls in the nearby vicinity.
These symbols are prohibited in Germany under laws banning the visible presentation of Nazi symbols.
Police report initial examinations indicate the fluid was most likely blood from a person.
"At present there remains no lead as to its origin; investigators are presently not aware of any injuries in relation with the occurrence," they added.
City officials announced they were working "to solve the incident" and have appealed to the public for information.
A high-ranking representative said the attack rendered him speechless and had to be solved rapidly.
"This event strikes at the very heart of Hanau and reawakens the trauma of the extremist attack five years ago," he posted on online, mentioning the death of nine victims by a gunman targeting individuals of immigrant origin in five years prior.
