Roughly fifty vehicles have been smeared with what seems to be human bodily fluid in the Germany's municipality of Hanau in proximity to Frankfurt, as reported by police.
Cars, walls and postboxes were defaced, in some cases with prohibited symbols, they reported in a official communication.
Law enforcement say they were contacted late on Wednesday, when a man noticed that a car in the Lamboy district of Hanau had been smeared with a red-colored liquid.
The substance had been drawn in the shape of a Nazi symbol, they added.
Police then found multiple other smeared vehicles and residential walls in the surrounding area.
Swastikas are banned in Germany under regulations outlawing the public display of Nazi-era symbols.
Law enforcement say early analysis indicate the substance was likely human blood.
"At present there remains no indication as to its source; investigators are currently not informed of any harm in connection with the occurrence," they stated.
City officials said they were working "to unravel the case" and have asked to the residents for information.
An important official stated the vandalism made him without words and required to be addressed rapidly.
"This incident hits the center of Hanau and reawakens the trauma of the extremist terrorist attack half a decade ago," he stated on social media, referring to the murder of nine people by a assailant aiming at individuals of immigrant origin in five years prior.
