Around 50 cars have been marked with what appears to be blood from a person in the Germany's city of Hanau near Frankfurt, according to law enforcement.
Automobiles, walls and postboxes were vandalized, occasionally with prohibited symbols, they announced in a release.
Officers say they were contacted during the night on Wednesday evening, when a resident noticed that a car in the Lamboy neighborhood of Hanau had been marked with a red-colored fluid.
The substance had been applied in the shape of a Nazi symbol, they reported.
Law enforcement then found many other vandalized cars and house walls in the nearby vicinity.
These symbols are prohibited in Germany under laws banning the public display of Nazi-era symbols.
Law enforcement report preliminary tests indicate the liquid was probably human blood.
"There is still no clue as to where it came from; officials are currently not aware of any physical harm in connection with the incident," they commented.
City officials stated they were trying "to unravel the mystery" and have requested to the residents for details.
An important official commented the incident rendered him without words and needed to be solved promptly.
"This incident affects the core of Hanau and reawakens the trauma of the extremist attack half a decade ago," he wrote on online, recalling the death of nine people by a shooter aiming at residents of migrant background in 2020.
