Area Police
Approximately 50 vehicles have been covered with what appears to be blood from a person in the German municipality of Hanau close to Frankfurt, according to law enforcement.
Vehicles, walls and postal boxes were defaced, in some cases with swastikas, they announced in a statement.
Police say they were contacted late on Wednesday evening, when a resident observed that a car in the Lamboy neighborhood of Hanau had been smeared with a red-colored fluid.
The liquid had been placed in the pattern of a Nazi symbol, they reported.
Police then found many other marked vehicles and residential walls in the nearby vicinity.
Nazi symbols are illegal in Germany under laws outlawing the public display of symbols from the Nazi era.
Law enforcement state preliminary tests show the liquid was most likely blood from a person.
"There is still no lead as to where it came from; authorities are not yet aware of any physical harm in connection with the event," they stated.
Local authorities said they were trying "to solve the mystery" and have appealed to the residents for details.
A senior political figure said the incident rendered him speechless and required to be addressed promptly.
"This event affects the very heart of Hanau and reawakens the trauma of the right-wing attack half a decade ago," he posted on online, mentioning the murder of nine individuals by a assailant targeting individuals of immigrant origin in 2020.
