Local Police
Around 50 vehicles have been marked with what appears to be human bodily fluid in the Germany's town of Hanau near Frankfurt, according to authorities.
Automobiles, building surfaces and postboxes were defaced, occasionally with prohibited symbols, they reported in a statement.
Law enforcement state they were contacted in the late hours on Wednesday, when a resident discovered that a automobile in the Lamboy neighborhood of Hanau had been marked with a red-colored substance.
The liquid had been placed in the shape of a Nazi symbol, they added.
Police then found numerous other smeared cars and house walls in the adjacent neighborhood.
Swastikas are prohibited in Germany under laws banning the public exhibition of Nazi symbols.
Law enforcement say early analysis suggest the liquid was most likely human blood.
"Currently there is no lead as to its source; officials are not yet cognizant of any harm in connection with the incident," they added.
Local authorities said they were working "to resolve the incident" and have asked to the community for information.
A high-ranking political figure said the attack rendered him without words and needed to be addressed rapidly.
"This event hits the center of Hanau and revives the pain of the far-right attack half a decade ago," he wrote on a platform, mentioning the killing of nine people by a shooter focusing on people of foreign heritage in 2020.
