Roughly 50 cars have been smeared with what seems to be blood from a person in the Germany's municipality of Hanau near Frankfurt, according to authorities.
Vehicles, building surfaces and mailboxes were defaced, in some cases with Nazi symbols, they announced in a statement.
Officers report they were notified during the night on Wednesday night, when a resident observed that a vehicle in the Lamboy area of Hanau had been smeared with a reddish-hued liquid.
The liquid had been applied in the pattern of a Nazi symbol, they reported.
Police then discovered many other vandalized cars and residential walls in the surrounding area.
Swastikas are illegal in Germany under regulations prohibiting the public exhibition of symbols from the Nazi era.
Police report early analysis show the liquid was most likely human blood.
"There is still no clue as to its origin; officials are currently not informed of any physical harm in relation with the event," they added.
Municipal representatives stated they were working "to resolve the case" and have requested to the community for tips.
A senior representative commented the attack made him speechless and needed to be resolved quickly.
"This act affects the core of Hanau and reawakens the trauma of the right-wing terrorist attack five years ago," he wrote on social media, mentioning the murder of nine people by a shooter focusing on people of foreign heritage in five years prior.
