Area Police
Around fifty cars have been marked with what appears to be human blood in the Germany's city of Hanau close to Frankfurt, according to law enforcement.
Vehicles, building surfaces and postboxes were defaced, in some cases with swastikas, they announced in a official communication.
Officers state they were alerted late on Wednesday, when a resident observed that a car in the Lamboy area of Hanau had been covered with a reddish liquid.
The liquid had been placed in the form of a swastika, they reported.
Officers then found numerous other vandalized cars and residential walls in the nearby vicinity.
Swastikas are illegal in Germany under regulations banning the public exhibition of Nazi-era symbols.
Officials say preliminary tests indicate the fluid was probably human bodily fluid.
"At present there remains no lead as to where it came from; officials are presently not informed of any physical harm in relation with the occurrence," they added.
City officials stated they were attempting "to unravel the case" and have asked to the residents for tips.
A senior official stated the incident rendered him without words and required to be addressed rapidly.
"This act strikes at the very heart of Hanau and revives the pain of the far-right terrorist attack half a decade ago," he posted on a platform, recalling the death of nine victims by a gunman aiming at residents of immigrant origin in February 2020.
