Roughly 50 cars have been covered with what appears to be human blood in the Germany's town of Hanau near Frankfurt, police confirm authorities.
Cars, building surfaces and postal boxes were marked, in some cases with prohibited symbols, they announced in a official communication.
Officers say they were contacted during the night on Wednesday, when a individual noticed that a car in the Lamboy district of Hanau had been smeared with a reddish-hued substance.
The substance had been drawn in the pattern of a Nazi symbol, they reported.
Police then discovered many other marked vehicles and residential walls in the surrounding area.
Swastikas are banned in Germany under laws outlawing the public exhibition of Nazi symbols.
Officials report early analysis suggest the liquid was probably blood from a person.
"At present there remains no clue as to its origin; investigators are not yet informed of any injuries in connection with the occurrence," they added.
Municipal representatives said they were working "to solve the mystery" and have appealed to the community for tips.
An important representative said the incident rendered him speechless and needed to be addressed rapidly.
"This event strikes at the very heart of Hanau and revives the wounds of the right-wing violent incident in 2020," he posted on a platform, recalling the killing of nine people by a shooter focusing on individuals of migrant background in 2020.
