Local Police
Around 50 cars have been marked with what seems to be human blood in the German town of Hanau close to Frankfurt, according to authorities.
Cars, exterior walls and postal boxes were defaced, sometimes with Nazi symbols, they reported in a statement.
Police report they were notified late on Wednesday night, when a resident noticed that a car in the Lamboy neighborhood of Hanau had been smeared with a reddish-hued substance.
The substance had been placed in the shape of a swastika, they reported.
Officers then found multiple other vandalized vehicles and building exteriors in the adjacent neighborhood.
These symbols are illegal in Germany under regulations banning the public exhibition of Nazi-era symbols.
Police report preliminary tests show the liquid was probably human blood.
"Currently there is no clue as to its origin; authorities are not yet cognizant of any physical harm in relation with the occurrence," they stated.
Municipal representatives announced they were attempting "to unravel the mystery" and have requested to the community for information.
An important political figure said the vandalism left him stunned and had to be resolved quickly.
"This incident affects the very heart of Hanau and reopens the pain of the far-right violent incident in 2020," he wrote on social media, recalling the death of nine individuals by a shooter targeting people of migrant background in five years prior.
