Around fifty cars have been marked with what appears to be human blood in the German city of Hanau near Frankfurt, according to authorities.
Automobiles, exterior walls and postal boxes were defaced, in some cases with swastikas, they announced in a release.
Officers say they were alerted in the late hours on Wednesday, when a individual discovered that a automobile in the Lamboy district of Hanau had been marked with a red-colored liquid.
The fluid had been applied in the form of a swastika, they added.
Police then discovered multiple other vandalized vehicles and building exteriors in the nearby vicinity.
These symbols are illegal in Germany under legislation prohibiting the public exhibition of symbols from the Nazi era.
Police state initial examinations suggest the liquid was likely human blood.
"There is still no indication as to its source; authorities are currently not informed of any harm in association with the event," they added.
Local authorities announced they were trying "to resolve the mystery" and have requested to the public for details.
A senior official commented the vandalism left him without words and had to be solved quickly.
"This event affects the very heart of Hanau and revives the wounds of the right-wing terrorist attack five years ago," he wrote on social media, mentioning the death of nine victims by a assailant aiming at people of immigrant origin in five years prior.
