Approximately 50 vehicles have been marked with what seems to be human blood in the Germany's town of Hanau in proximity to Frankfurt, as reported by authorities.
Cars, exterior walls and postal boxes were defaced, sometimes with Nazi symbols, they announced in a official communication.
Police state they were alerted late on Wednesday, when a resident observed that a vehicle in the Lamboy neighborhood of Hanau had been covered with a reddish-hued substance.
The liquid had been placed in the shape of a swastika, they added.
Officers then found multiple other vandalized vehicles and house walls in the adjacent neighborhood.
Nazi symbols are banned in Germany under regulations outlawing the public display of symbols from the Nazi era.
Law enforcement report initial examinations suggest the liquid was most likely blood from a person.
"There is still no clue as to where it came from; authorities are currently not cognizant of any injuries in relation with the incident," they commented.
City officials said they were working "to resolve the mystery" and have appealed to the residents for details.
A senior official said the incident made him stunned and required to be solved promptly.
"This event affects the very heart of Hanau and reopens the pain of the right-wing terrorist attack five years ago," he posted on online, recalling the killing of nine individuals by a shooter aiming at people of foreign heritage in February 2020.
