Approximately 50 automobiles have been covered with what appears to be human blood in the German city of Hanau in proximity to Frankfurt, police confirm authorities.
Cars, exterior walls and postboxes were defaced, in some cases with swastikas, they announced in a official communication.
Police say they were notified late on Wednesday night, when a resident discovered that a car in the Lamboy district of Hanau had been smeared with a reddish-hued fluid.
The liquid had been applied in the shape of a swastika, they reported.
Law enforcement then found multiple other smeared automobiles and house walls in the adjacent neighborhood.
Swastikas are banned in Germany under regulations prohibiting the public display of Nazi symbols.
Officials say initial examinations show the substance was most likely blood from a person.
"At present there remains no clue as to its source; authorities are not yet informed of any harm in connection with the event," they stated.
City officials said they were attempting "to resolve the mystery" and have appealed to the residents for tips.
A senior official commented the attack made him without words and needed to be resolved promptly.
"This event affects the core of Hanau and reopens the pain of the far-right terrorist attack half a decade ago," he stated on social media, recalling the death of nine victims by a shooter focusing on individuals of foreign heritage in five years prior.
