Roughly 50 vehicles have been covered with what seems to be human bodily fluid in the German municipality of Hanau in proximity to Frankfurt, according to police.
Vehicles, exterior walls and postal boxes were marked, sometimes with prohibited symbols, they reported in a statement.
Law enforcement say they were notified during the night on Wednesday night, when a resident discovered that a car in the Lamboy district of Hanau had been marked with a red-colored liquid.
The liquid had been placed in the form of a banned symbol, they reported.
Police then discovered many other marked cars and building exteriors in the adjacent neighborhood.
Nazi symbols are banned in Germany under laws prohibiting the public display of Nazi-era symbols.
Officials state preliminary tests show the fluid was likely human blood.
"At present there remains no indication as to where it came from; authorities are not yet cognizant of any harm in connection with the incident," they added.
Municipal representatives stated they were trying "to unravel the incident" and have requested to the residents for details.
An important representative said the incident made him without words and required to be addressed promptly.
"This incident hits the center of Hanau and reopens the pain of the far-right terrorist attack half a decade ago," he posted on a platform, mentioning the killing of nine individuals by a gunman aiming at people of migrant background in five years prior.
