Roughly 50 vehicles have been marked with what seems to be blood from a person in the Germany's city of Hanau near Frankfurt, as reported by law enforcement.
Cars, building surfaces and mailboxes were defaced, occasionally with Nazi symbols, they stated in a official communication.
Law enforcement report they were alerted during the night on Wednesday night, when a man observed that a car in the Lamboy neighborhood of Hanau had been smeared with a reddish substance.
The fluid had been drawn in the form of a banned symbol, they reported.
Officers then located many other vandalized vehicles and residential walls in the adjacent neighborhood.
Swastikas are illegal in Germany under legislation banning the public exhibition of symbols from the Nazi era.
Police say early analysis show the substance was probably human bodily fluid.
"Currently there is no lead as to its source; officials are not yet aware of any physical harm in connection with the incident," they added.
Municipal representatives stated they were working "to unravel the mystery" and have requested to the public for details.
An important representative said the incident left him without words and needed to be resolved rapidly.
"This event hits the center of Hanau and reopens the pain of the right-wing violent incident five years ago," he posted on social media, mentioning the death of nine individuals by a gunman targeting residents of foreign heritage in February 2020.
