Around fifty cars have been covered with what appears to be human bodily fluid in the German town of Hanau close to Frankfurt, according to authorities.
Cars, walls and mailboxes were marked, sometimes with swastikas, they reported in a release.
Law enforcement state they were alerted late on Wednesday, when a resident observed that a automobile in the Lamboy neighborhood of Hanau had been covered with a reddish-hued liquid.
The liquid had been drawn in the form of a swastika, they added.
Officers then located numerous other vandalized cars and residential walls in the nearby vicinity.
Swastikas are prohibited in Germany under regulations prohibiting the visible presentation of Nazi-era symbols.
Officials say preliminary tests suggest the liquid was most likely blood from a person.
"Currently there is no clue as to where it came from; authorities are currently not aware of any injuries in association with the event," they added.
City officials said they were trying "to resolve the case" and have appealed to the community for details.
A senior official said the incident made him stunned and needed to be solved quickly.
"This act affects the core of Hanau and reopens the wounds of the right-wing terrorist attack in 2020," he wrote on online, mentioning the death of nine people by a assailant focusing on people of migrant background in 2020.
