Area Police
Approximately 50 cars have been smeared with what seems to be human bodily fluid in the Germany's city of Hanau close to Frankfurt, according to law enforcement.
Automobiles, building surfaces and postal boxes were defaced, occasionally with Nazi symbols, they announced in a statement.
Police state they were alerted during the night on Wednesday, when a resident observed that a vehicle in the Lamboy area of Hanau had been marked with a red-colored substance.
The liquid had been placed in the shape of a banned symbol, they added.
Officers then discovered multiple other vandalized vehicles and building exteriors in the adjacent neighborhood.
Nazi symbols are illegal in Germany under regulations banning the public display of symbols from the Nazi era.
Law enforcement report initial examinations indicate the substance was most likely blood from a person.
"Currently there is no lead as to its origin; investigators are not yet informed of any physical harm in relation with the occurrence," they stated.
Local authorities announced they were working "to unravel the incident" and have appealed to the public for information.
An important political figure commented the vandalism left him speechless and needed to be resolved promptly.
"This act strikes at the very heart of Hanau and reopens the pain of the right-wing attack half a decade ago," he wrote on online, mentioning the death of nine individuals by a shooter focusing on people of foreign heritage in five years prior.
