Area Law Enforcement
Around 50 automobiles have been marked with what seems to be human blood in the Germany's city of Hanau close to Frankfurt, according to law enforcement.
Cars, building surfaces and postal boxes were defaced, in some cases with prohibited symbols, they stated in a release.
Police state they were alerted late on Wednesday evening, when a individual discovered that a car in the Lamboy district of Hanau had been marked with a reddish fluid.
The liquid had been placed in the pattern of a swastika, they added.
Officers then found many other smeared vehicles and house walls in the adjacent neighborhood.
Swastikas are illegal in Germany under regulations prohibiting the public exhibition of Nazi symbols.
Law enforcement say early analysis suggest the fluid was most likely human bodily fluid.
"Currently there is no clue as to its source; investigators are not yet cognizant of any physical harm in association with the incident," they added.
City officials said they were working "to unravel the mystery" and have asked to the public for details.
A high-ranking official commented the attack rendered him stunned and required to be resolved rapidly.
"This event strikes at the very heart of Hanau and reawakens the pain of the extremist terrorist attack five years ago," he wrote on social media, referring to the death of nine individuals by a gunman focusing on residents of foreign heritage in February 2020.
