Local Police
Approximately fifty cars have been smeared with what appears to be human blood in the German municipality of Hanau close to Frankfurt, police confirm authorities.
Cars, walls and postal boxes were vandalized, sometimes with Nazi symbols, they reported in a release.
Officers say they were alerted in the late hours on Wednesday, when a resident discovered that a vehicle in the Lamboy neighborhood of Hanau had been covered with a red-colored substance.
The liquid had been drawn in the shape of a swastika, they stated.
Law enforcement then discovered multiple other vandalized automobiles and residential walls in the nearby vicinity.
These symbols are illegal in Germany under legislation banning the visible presentation of symbols from the Nazi era.
Law enforcement say preliminary tests show the substance was probably human blood.
"At present there remains no clue as to its source; officials are not yet aware of any harm in connection with the incident," they added.
Local authorities said they were working "to resolve the mystery" and have requested to the community for tips.
A high-ranking political figure stated the attack made him speechless and needed to be addressed promptly.
"This event strikes at the center of Hanau and reawakens the pain of the extremist violent incident five years ago," he posted on a platform, referring to the death of nine individuals by a gunman aiming at individuals of migrant background in five years prior.
