Local Police
Around 50 cars have been covered with what appears to be blood from a person in the Germany's municipality of Hanau near Frankfurt, police confirm police.
Automobiles, exterior walls and postal boxes were vandalized, in some cases with prohibited symbols, they announced in a statement.
Officers say they were alerted late on Wednesday night, when a man noticed that a automobile in the Lamboy area of Hanau had been marked with a reddish substance.
The liquid had been placed in the form of a Nazi symbol, they added.
Law enforcement then located many other marked automobiles and residential walls in the surrounding area.
Swastikas are illegal in Germany under legislation outlawing the public display of symbols from the Nazi era.
Police say initial examinations suggest the fluid was most likely human bodily fluid.
"There is still no lead as to where it came from; officials are presently not cognizant of any physical harm in association with the occurrence," they stated.
Municipal representatives said they were working "to resolve the mystery" and have appealed to the public for information.
An important official stated the incident left him speechless and required to be solved promptly.
"This act strikes at the very heart of Hanau and reawakens the trauma of the extremist violent incident five years ago," he stated on online, recalling the killing of nine individuals by a shooter aiming at people of foreign heritage in 2020.
