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 authorities.
Cars, exterior walls and mailboxes were vandalized, occasionally with swastikas, they stated in a statement.
Police say they were notified late on Wednesday, when a resident observed that a vehicle in the Lamboy district of Hanau had been marked with a red-colored substance.
The liquid had been placed in the pattern of a Nazi symbol, they stated.
Law enforcement then discovered multiple other marked cars and residential walls in the adjacent neighborhood.
Swastikas are banned in Germany under legislation outlawing the public exhibition of Nazi-era symbols.
Police state preliminary tests suggest the substance was likely human bodily fluid.
"Currently there is no clue as to its origin; investigators are presently not informed of any physical harm in connection with the event," they stated.
Local authorities stated they were working "to resolve the case" and have requested to the residents for tips.
A high-ranking political figure said the attack left him speechless and had to be resolved quickly.
"This event affects the very heart of Hanau and reopens the wounds of the far-right violent incident half a decade ago," he stated on a platform, referring to the killing of nine people by a assailant aiming at people of foreign heritage in five years prior.
