Area Police
Around fifty cars have been covered with what appears to be human bodily fluid in the Germany's municipality of Hanau near Frankfurt, according to police.
Vehicles, building surfaces and postboxes were defaced, occasionally with prohibited symbols, they announced in a statement.
Law enforcement say they were contacted during the night on Wednesday, when a man discovered that a vehicle in the Lamboy area of Hanau had been smeared with a reddish liquid.
The liquid had been drawn in the form of a Nazi symbol, they stated.
Law enforcement then discovered many other vandalized automobiles and building exteriors in the adjacent neighborhood.
Nazi symbols are illegal in Germany under legislation banning the public display of Nazi symbols.
Officials report initial examinations indicate the substance was most likely blood from a person.
"There is still no clue as to its source; authorities are currently not informed of any injuries in connection with the occurrence," they added.
Local authorities said they were attempting "to resolve the case" and have appealed to the public for information.
A senior official stated the vandalism left him without words and had to be addressed rapidly.
"This event strikes at the core of Hanau and reawakens the pain of the right-wing violent incident half a decade ago," he posted on online, referring to the murder of nine people by a gunman focusing on residents of migrant background in five years prior.
