Area Law Enforcement
Approximately 50 automobiles have been covered with what seems to be human blood in the Germany's town of Hanau close to Frankfurt, according to law enforcement.
Cars, exterior walls and postboxes were marked, sometimes with Nazi symbols, they stated in a release.
Police say they were alerted during the night on Wednesday night, when a individual observed that a car in the Lamboy district of Hanau had been marked with a red-colored substance.
The liquid had been placed in the shape of a Nazi symbol, they added.
Law enforcement then discovered many other marked automobiles and house walls in the nearby vicinity.
Swastikas are illegal in Germany under regulations banning the visible presentation of Nazi symbols.
Law enforcement say early analysis suggest the liquid was most likely human blood.
"At present there remains no lead as to where it came from; investigators are not yet aware of any injuries in relation with the occurrence," they added.
Local authorities stated they were trying "to unravel the mystery" and have requested to the residents for tips.
A senior political figure commented the vandalism left him speechless and needed to be solved rapidly.
"This act affects the center of Hanau and reopens the trauma of the extremist attack half a decade ago," he stated on social media, mentioning the murder of nine victims by a shooter aiming at residents of immigrant origin in five years prior.
