Approximately 50 cars have been covered with what appears to be human blood in the German municipality of Hanau near Frankfurt, as reported by police.
Automobiles, exterior walls and postal boxes were marked, sometimes with prohibited symbols, they announced in a release.
Police say they were alerted in the late hours on Wednesday, when a resident noticed that a vehicle in the Lamboy neighborhood of Hanau had been smeared with a reddish liquid.
The substance had been placed in the pattern of a banned symbol, they stated.
Officers then located many other vandalized cars and residential walls in the surrounding area.
These symbols are banned in Germany under regulations banning the visible presentation of Nazi symbols.
Officials state preliminary tests show the fluid was most likely blood from a person.
"There is still no clue as to its source; authorities are presently not informed of any physical harm in connection with the event," they stated.
City officials stated they were working "to unravel the mystery" and have appealed to the community for tips.
An important representative said the attack made him without words and had to be addressed quickly.
"This act hits the core of Hanau and reawakens the trauma of the extremist violent incident half a decade ago," he posted on online, recalling the death of nine people by a gunman aiming at individuals of foreign heritage in five years prior.
