Roughly fifty vehicles have been smeared with what appears to be human blood in the Germany's town of Hanau close to Frankfurt, according to police.
Cars, exterior walls and mailboxes were vandalized, sometimes with Nazi symbols, they reported in a release.
Police say they were notified in the late hours on Wednesday, when a individual discovered that a car in the Lamboy area of Hanau had been smeared with a red-colored fluid.
The liquid had been applied in the shape of a swastika, they added.
Police then found numerous other smeared vehicles and house walls in the nearby vicinity.
These symbols are prohibited in Germany under laws outlawing the public exhibition of Nazi-era symbols.
Law enforcement state early analysis show the fluid was probably human bodily fluid.
"Currently there is no clue as to where it came from; investigators are not yet aware of any injuries in connection with the occurrence," they commented.
Local authorities said they were attempting "to solve the mystery" and have appealed to the public for tips.
An important official commented the attack rendered him stunned and needed to be resolved promptly.
"This incident affects the core of Hanau and revives the wounds of the extremist violent incident five years ago," he posted on online, recalling the death of nine victims by a gunman aiming at residents of immigrant origin in five years prior.
