Area Police
Roughly 50 vehicles have been marked with what appears to be blood from a person in the Germany's municipality of Hanau near Frankfurt, according to authorities.
Cars, building surfaces and postal boxes were marked, sometimes with Nazi symbols, they announced in a release.
Law enforcement say they were alerted in the late hours on Wednesday evening, when a resident noticed that a car in the Lamboy area of Hanau had been covered with a reddish fluid.
The substance had been applied in the form of a swastika, they stated.
Police then discovered numerous other marked automobiles and building exteriors in the nearby vicinity.
Swastikas are prohibited in Germany under regulations prohibiting the visible presentation of symbols from the Nazi era.
Officials state preliminary tests indicate the substance was most likely human bodily fluid.
"At present there remains no indication as to its source; authorities are not yet cognizant of any harm in relation with the incident," they commented.
City officials said they were trying "to solve the case" and have asked to the residents for details.
A high-ranking political figure stated the incident left him without words and needed to be resolved rapidly.
"This event hits the center of Hanau and revives the pain of the extremist attack half a decade ago," he posted on social media, mentioning the killing of nine people by a assailant aiming at residents of migrant background in 2020.
