Area Police
Roughly 50 vehicles have been marked with what seems to be human blood in the Germany's municipality of Hanau near Frankfurt, according to police.
Cars, walls and mailboxes were defaced, occasionally with prohibited symbols, they announced in a release.
Officers report they were notified during the night on Wednesday evening, when a individual observed that a car in the Lamboy area of Hanau had been marked with a reddish fluid.
The liquid had been placed in the form of a Nazi symbol, they reported.
Officers then found numerous other smeared cars and house walls in the adjacent neighborhood.
Nazi symbols are illegal in Germany under legislation prohibiting the visible presentation of Nazi symbols.
Officials report preliminary tests show the fluid was probably human bodily fluid.
"At present there remains no indication as to its origin; authorities are presently not cognizant of any harm in connection with the event," they added.
Municipal representatives announced they were trying "to unravel the mystery" and have asked to the public for details.
A senior political figure stated the attack left him speechless and had to be solved promptly.
"This event hits the very heart of Hanau and revives the trauma of the far-right attack half a decade ago," he stated on online, recalling the killing of nine victims by a gunman focusing on people of migrant background in 2020.
