Local Police
Roughly 50 cars have been smeared with what seems to be blood from a person in the Germany's town of Hanau close to Frankfurt, according to authorities.
Automobiles, exterior walls and postal boxes were defaced, in some cases with Nazi symbols, they reported in a statement.
Police say they were alerted during the night on Wednesday night, when a man noticed that a vehicle in the Lamboy district of Hanau had been covered with a reddish-hued substance.
The fluid had been drawn in the form of a banned symbol, they added.
Law enforcement then located numerous other smeared vehicles and house walls in the surrounding area.
These symbols are prohibited in Germany under laws outlawing the public display of symbols from the Nazi era.
Law enforcement report preliminary tests suggest the substance was probably blood from a person.
"There is still no clue as to its source; investigators are presently not cognizant of any harm in relation with the incident," they commented.
Local authorities stated they were attempting "to unravel the mystery" and have appealed to the residents for details.
A high-ranking political figure said the attack left him stunned and needed to be addressed rapidly.
"This incident strikes at the core of Hanau and reopens the wounds of the right-wing violent incident half a decade ago," he posted on a platform, mentioning the murder of nine individuals by a shooter focusing on people of migrant background in February 2020.
