Area Police
Around fifty cars have been smeared with what appears to be blood from a person in the Germany's city of Hanau near Frankfurt, according to authorities.
Vehicles, walls and postboxes were defaced, sometimes with swastikas, they reported in a release.
Police say they were notified during the night on Wednesday evening, when a resident discovered that a automobile in the Lamboy area of Hanau had been covered with a reddish liquid.
The fluid had been drawn in the pattern of a banned symbol, they added.
Law enforcement then discovered numerous other vandalized vehicles and house walls in the surrounding area.
Swastikas are illegal in Germany under legislation prohibiting the public exhibition of Nazi symbols.
Officials say initial examinations show the substance was probably blood from a person.
"Currently there is no indication as to its source; investigators are presently not aware of any injuries in relation with the event," they added.
Local authorities said they were attempting "to solve the incident" and have asked to the community for information.
A senior political figure commented the attack rendered him without words and had to be resolved promptly.
"This event hits the center of Hanau and revives the wounds of the right-wing terrorist attack half a decade ago," he wrote on social media, mentioning the murder of nine victims by a gunman aiming at residents of migrant background in 2020.
