Area Law Enforcement
Roughly 50 cars have been marked with what appears to be human bodily fluid in the Germany's city of Hanau near Frankfurt, according to police.
Cars, building surfaces and postal boxes were marked, in some cases with swastikas, they announced in a statement.
Officers state they were contacted during the night on Wednesday, when a resident noticed that a car in the Lamboy district of Hanau had been covered with a reddish fluid.
The liquid had been placed in the form of a banned symbol, they added.
Law enforcement then located multiple other marked automobiles and building exteriors in the adjacent neighborhood.
Nazi symbols are prohibited in Germany under legislation banning the public display of symbols from the Nazi era.
Officials say early analysis show the liquid was most likely blood from a person.
"Currently there is no clue as to where it came from; authorities are not yet cognizant of any harm in relation with the occurrence," they added.
Municipal representatives said they were attempting "to unravel the incident" and have asked to the residents for information.
A senior representative commented the vandalism left him stunned and had to be addressed promptly.
"This act hits the center of Hanau and reawakens the trauma of the right-wing violent incident five years ago," he wrote on a platform, referring to the murder of nine individuals by a gunman targeting residents of foreign heritage in five years prior.
