Roughly 50 vehicles have been marked with what appears to be human blood in the Germany's town of Hanau close to Frankfurt, police confirm law enforcement.
Cars, walls and mailboxes were defaced, occasionally with swastikas, they announced in a statement.
Officers say they were alerted during the night on Wednesday, when a resident noticed that a vehicle in the Lamboy district of Hanau had been marked with a reddish fluid.
The fluid had been placed in the shape of a Nazi symbol, they added.
Law enforcement then discovered numerous other marked cars and building exteriors in the surrounding area.
These symbols are illegal in Germany under legislation prohibiting the visible presentation of Nazi symbols.
Police report early analysis show the substance was likely human bodily fluid.
"There is still no lead as to where it came from; officials are not yet aware of any harm in association with the event," they commented.
City officials said they were trying "to solve the mystery" and have requested to the public for details.
A high-ranking political figure said the attack rendered him without words and required to be resolved rapidly.
"This event hits the center of Hanau and reopens the wounds of the right-wing terrorist attack half a decade ago," he posted on online, referring to the murder of nine individuals by a shooter aiming at individuals of immigrant origin in five years prior.
