Approximately 50 vehicles have been covered with what seems to be human blood in the German city of Hanau in proximity to Frankfurt, according to authorities.
Cars, walls and postboxes were defaced, in some cases with swastikas, they announced in a official communication.
Law enforcement report they were notified during the night on Wednesday night, when a man discovered that a car in the Lamboy neighborhood of Hanau had been covered with a reddish substance.
The liquid had been applied in the pattern of a banned symbol, they stated.
Police then found multiple other smeared automobiles and house walls in the nearby vicinity.
Nazi symbols are prohibited in Germany under legislation banning the visible presentation of symbols from the Nazi era.
Law enforcement say preliminary tests suggest the fluid was most likely human bodily fluid.
"At present there remains no clue as to its source; investigators are presently not informed of any harm in association with the event," they stated.
Local authorities said they were attempting "to resolve the incident" and have requested to the residents for tips.
A senior political figure said the attack made him without words and had to be solved rapidly.
"This event hits the very heart of Hanau and revives the pain of the right-wing terrorist attack half a decade ago," he posted on social media, mentioning the murder of nine people by a shooter focusing on residents of immigrant origin in February 2020.
