Area Police
Approximately 50 cars have been covered with what seems to be human blood in the German city of Hanau close to Frankfurt, according to police.
Vehicles, exterior walls and postboxes were defaced, sometimes with swastikas, they stated in a statement.
Officers say they were notified late on Wednesday, when a resident noticed that a vehicle in the Lamboy district of Hanau had been smeared with a reddish-hued liquid.
The liquid had been drawn in the shape of a banned symbol, they added.
Law enforcement then found numerous other smeared vehicles and residential walls in the surrounding area.
Nazi symbols are prohibited in Germany under regulations banning the public exhibition of Nazi symbols.
Officials report initial examinations suggest the substance was likely blood from a person.
"There is still no lead as to its source; investigators are not yet cognizant of any harm in relation with the occurrence," they stated.
Municipal representatives stated they were attempting "to resolve the case" and have requested to the public for information.
An important representative said the vandalism rendered him without words and needed to be resolved rapidly.
"This event hits the very heart of Hanau and reawakens the wounds of the far-right terrorist attack half a decade ago," he posted on a platform, referring to the murder of nine victims by a gunman targeting residents of immigrant origin in 2020.
