Local Police
Around fifty vehicles have been smeared with what appears to be human blood in the Germany's city of Hanau close to Frankfurt, police confirm authorities.
Automobiles, walls and postal boxes were marked, occasionally with swastikas, they reported in a release.
Officers say they were notified during the night on Wednesday evening, when a man observed that a automobile in the Lamboy district of Hanau had been covered with a reddish-hued substance.
The substance had been applied in the pattern of a swastika, they added.
Police then discovered multiple other vandalized vehicles and residential walls in the surrounding area.
Nazi symbols are prohibited in Germany under legislation prohibiting the public display of Nazi-era symbols.
Officials say preliminary tests suggest the substance was most likely human blood.
"There is still no clue as to where it came from; authorities are currently not cognizant of any physical harm in association with the incident," they stated.
Local authorities said they were working "to solve the mystery" and have requested to the community for tips.
A senior political figure said the vandalism rendered him stunned and had to be resolved promptly.
"This event affects the core of Hanau and revives the trauma of the right-wing violent incident half a decade ago," he posted on social media, referring to the death of nine individuals by a shooter targeting individuals of immigrant origin in 2020.
