Local Police
Approximately fifty cars have been covered with what seems to be human blood in the Germany's town of Hanau close to Frankfurt, according to authorities.
Cars, exterior walls and postboxes were vandalized, occasionally with Nazi symbols, they stated in a statement.
Police say they were alerted late on Wednesday evening, when a resident discovered that a car in the Lamboy area of Hanau had been smeared with a reddish-hued substance.
The liquid had been drawn in the form of a swastika, they added.
Law enforcement then located many other smeared automobiles and house walls in the nearby vicinity.
Swastikas are prohibited in Germany under laws outlawing the public display of Nazi-era symbols.
Officials state initial examinations suggest the substance was most likely human bodily fluid.
"At present there remains no lead as to its origin; officials are currently not informed of any injuries in connection with the event," they commented.
Municipal representatives said they were trying "to solve the mystery" and have asked to the public for information.
An important official said the vandalism made him without words and needed to be addressed promptly.
"This incident strikes at the very heart of Hanau and revives the pain of the far-right terrorist attack five years ago," he wrote on online, mentioning the death of nine people by a assailant targeting people of immigrant origin in five years prior.
