Around 50 cars have been covered with what appears to be human blood in the Germany's town of Hanau near Frankfurt, as reported by police.
Automobiles, exterior walls and postboxes were marked, occasionally with prohibited symbols, they stated in a statement.
Law enforcement say they were notified late on Wednesday night, when a individual discovered that a car in the Lamboy neighborhood of Hanau had been covered with a reddish liquid.
The liquid had been drawn in the form of a banned symbol, they stated.
Law enforcement then found multiple other vandalized cars and building exteriors in the nearby vicinity.
Swastikas are banned in Germany under regulations outlawing the public display of symbols from the Nazi era.
Police say early analysis indicate the substance was probably blood from a person.
"Currently there is no lead as to its source; investigators are presently not aware of any harm in connection with the event," they stated.
Municipal representatives announced they were working "to resolve the mystery" and have appealed to the community for information.
A senior official stated the incident made him stunned and had to be solved promptly.
"This act affects the core of Hanau and revives the wounds of the far-right violent incident half a decade ago," he wrote on a platform, referring to the killing of nine individuals by a shooter aiming at residents of migrant background in 2020.
