Area Police
Roughly fifty vehicles have been covered with what appears to be blood from a person in the Germany's city of Hanau close to Frankfurt, according to police.
Cars, building surfaces and mailboxes were marked, sometimes with swastikas, they reported in a release.
Law enforcement state they were contacted late on Wednesday, when a resident observed that a car in the Lamboy area of Hanau had been covered with a red-colored liquid.
The liquid had been applied in the form of a swastika, they added.
Police then located numerous other smeared automobiles and house walls in the nearby vicinity.
Swastikas are prohibited in Germany under regulations banning the public exhibition of Nazi-era symbols.
Officials state initial examinations indicate the substance was likely blood from a person.
"At present there remains no clue as to its source; officials are currently not informed of any physical harm in relation with the incident," they added.
Local authorities said they were working "to resolve the incident" and have asked to the community for information.
A high-ranking political figure stated the vandalism made him speechless and required to be addressed rapidly.
"This act affects the center of Hanau and revives the trauma of the extremist violent incident in 2020," he posted on a platform, recalling the killing of nine individuals by a gunman focusing on residents of migrant background in five years prior.
