Local Police
Around 50 vehicles have been marked with what appears to be human blood in the Germany's town of Hanau near Frankfurt, police confirm authorities.
Cars, walls and postboxes were defaced, sometimes with swastikas, they reported in a statement.
Police say they were notified during the night on Wednesday evening, when a man discovered that a automobile in the Lamboy neighborhood of Hanau had been marked with a red-colored liquid.
The substance had been applied in the shape of a swastika, they added.
Police then found many other smeared automobiles and house walls in the adjacent neighborhood.
Nazi symbols are prohibited in Germany under laws prohibiting the visible presentation of Nazi-era symbols.
Law enforcement state initial examinations suggest the substance was probably blood from a person.
"At present there remains no clue as to its origin; authorities are not yet cognizant of any physical harm in relation with the occurrence," they stated.
Local authorities announced they were working "to solve the case" and have appealed to the residents for details.
A senior representative commented the incident rendered him stunned and had to be addressed quickly.
"This act strikes at the center of Hanau and reawakens the pain of the far-right terrorist attack five years ago," he stated on social media, recalling the killing of nine victims by a shooter aiming at people of foreign heritage in 2020.
