Area Police
Approximately 50 automobiles have been covered with what seems to be blood from a person in the Germany's city of Hanau in proximity to Frankfurt, according to police.
Cars, exterior walls and postboxes were vandalized, occasionally with prohibited symbols, they stated in a official communication.
Law enforcement report they were notified during the night on Wednesday night, when a resident noticed that a vehicle in the Lamboy district of Hanau had been covered with a reddish-hued fluid.
The liquid had been placed in the shape of a swastika, they reported.
Law enforcement then found multiple other marked vehicles and residential walls in the surrounding area.
These symbols are banned in Germany under legislation banning the public display of Nazi-era symbols.
Law enforcement report early analysis suggest the substance was probably human blood.
"At present there remains no indication as to its origin; officials are presently not informed of any physical harm in association with the occurrence," they added.
Municipal representatives stated they were trying "to unravel the mystery" and have appealed to the residents for information.
A high-ranking representative said the incident made him without words and had to be addressed rapidly.
"This event hits the very heart of Hanau and reawakens the trauma of the far-right terrorist attack half a decade ago," he posted on a platform, referring to the death of nine individuals by a shooter focusing on individuals of migrant background in five years prior.
