Area Police
Roughly 50 vehicles have been covered with what appears to be human blood in the Germany's municipality of Hanau in proximity to Frankfurt, according to law enforcement.
Automobiles, exterior walls and postboxes were vandalized, sometimes with swastikas, they announced in a official communication.
Officers state they were contacted late on Wednesday evening, when a resident discovered that a vehicle in the Lamboy area of Hanau had been marked with a reddish-hued substance.
The substance had been applied in the pattern of a banned symbol, they stated.
Police then found numerous other vandalized cars and house walls in the nearby vicinity.
Swastikas are illegal in Germany under regulations outlawing the public display of Nazi-era symbols.
Police state initial examinations show the fluid was probably human blood.
"At present there remains no lead as to where it came from; authorities are not yet informed of any harm in connection with the incident," they stated.
Municipal representatives announced they were attempting "to unravel the case" and have appealed to the residents for details.
A senior representative said the attack left him without words and needed to be solved promptly.
"This incident strikes at the core of Hanau and reawakens the pain of the right-wing attack five years ago," he posted on online, referring to the killing of nine people by a shooter aiming at individuals of migrant background in five years prior.
