Area Police
Around 50 vehicles have been covered with what seems to be human bodily fluid in the Germany's city of Hanau near Frankfurt, according to law enforcement.
Automobiles, building surfaces and postal boxes were marked, in some cases with swastikas, they reported in a release.
Police say they were contacted during the night on Wednesday, when a resident noticed that a car in the Lamboy neighborhood of Hanau had been smeared with a reddish-hued fluid.
The substance had been applied in the shape of a banned symbol, they reported.
Law enforcement then discovered multiple other smeared vehicles and building exteriors in the nearby vicinity.
Nazi symbols are prohibited in Germany under legislation prohibiting the visible presentation of symbols from the Nazi era.
Police state initial examinations show the substance was probably human blood.
"There is still no lead as to where it came from; officials are presently not cognizant of any physical harm in association with the event," they commented.
Local authorities stated they were attempting "to solve the case" and have asked to the public for details.
A senior official said the vandalism rendered him stunned and had to be resolved rapidly.
"This event strikes at the core of Hanau and revives the trauma of the right-wing violent incident five years ago," he stated on social media, referring to the murder of nine victims by a assailant focusing on individuals of migrant background in five years prior.
