Around fifty cars have been marked with what appears to be human blood in the Germany's town of Hanau close to Frankfurt, as reported by police.
Cars, exterior walls and mailboxes were marked, sometimes with Nazi symbols, they stated in a release.
Law enforcement state they were alerted late on Wednesday evening, when a man discovered that a car in the Lamboy neighborhood of Hanau had been covered with a red-colored substance.
The liquid had been applied in the shape of a swastika, they added.
Law enforcement then found many other smeared vehicles and residential walls in the nearby vicinity.
Nazi symbols are illegal in Germany under laws banning the public exhibition of Nazi symbols.
Officials say preliminary tests show the substance was probably human blood.
"Currently there is no clue as to its origin; authorities are presently not aware of any physical harm in connection with the incident," they added.
Municipal representatives said they were working "to solve the incident" and have appealed to the community for details.
A senior official stated the incident rendered him speechless and needed to be resolved promptly.
"This event affects the very heart of Hanau and revives the wounds of the right-wing terrorist attack five years ago," he posted on a platform, mentioning the killing of nine victims by a shooter targeting individuals of migrant background in February 2020.
