Area Police
Roughly 50 vehicles have been covered with what appears to be human blood in the Germany's city of Hanau near Frankfurt, according to authorities.
Automobiles, walls and mailboxes were defaced, sometimes with swastikas, they reported in a release.
Officers say they were notified during the night on Wednesday, when a man observed that a car in the Lamboy area of Hanau had been smeared with a reddish-hued fluid.
The fluid had been applied in the shape of a Nazi symbol, they reported.
Law enforcement then found multiple other marked vehicles and building exteriors in the adjacent neighborhood.
Nazi symbols are prohibited in Germany under regulations outlawing the public exhibition of symbols from the Nazi era.
Law enforcement say early analysis indicate the liquid was most likely blood from a person.
"There is still no indication as to its source; officials are not yet aware of any injuries in association with the occurrence," they added.
City officials said they were trying "to solve the case" and have requested to the residents for tips.
A senior political figure commented the vandalism rendered him stunned and needed to be addressed quickly.
"This act hits the very heart of Hanau and reawakens the wounds of the far-right attack five years ago," he posted on social media, mentioning the killing of nine victims by a gunman targeting residents of foreign heritage in 2020.
