Area Police
Around 50 automobiles have been covered with what seems to be human blood in the Germany's municipality of Hanau close to Frankfurt, as reported by authorities.
Cars, exterior walls and postboxes were defaced, sometimes with Nazi symbols, they stated in a statement.
Officers say they were contacted late on Wednesday night, when a man noticed that a vehicle in the Lamboy area of Hanau had been marked with a reddish substance.
The liquid had been applied in the shape of a banned symbol, they added.
Law enforcement then located numerous other smeared cars and house walls in the adjacent neighborhood.
Nazi symbols are prohibited in Germany under laws prohibiting the visible presentation of Nazi-era symbols.
Police report preliminary tests suggest the liquid was likely human blood.
"At present there remains no lead as to its source; investigators are not yet cognizant of any physical harm in connection with the occurrence," they added.
City officials stated they were working "to resolve the incident" and have requested to the community for tips.
A senior official stated the incident rendered him speechless and required to be solved rapidly.
"This event strikes at the very heart of Hanau and reawakens the pain of the right-wing violent incident five years ago," he wrote on online, mentioning the murder of nine people by a assailant focusing on individuals of foreign heritage in February 2020.
