Area Police
Roughly 50 vehicles have been covered with what seems to be blood from a person in the German city of Hanau close to Frankfurt, as reported by authorities.
Cars, building surfaces and postal boxes were defaced, sometimes with prohibited symbols, they reported in a official communication.
Police say they were notified in the late hours on Wednesday, when a man observed that a automobile in the Lamboy district of Hanau had been marked with a red-colored substance.
The liquid had been drawn in the pattern of a swastika, they reported.
Officers then discovered many other smeared automobiles and residential walls in the nearby vicinity.
Swastikas are banned in Germany under regulations prohibiting the public exhibition of Nazi-era symbols.
Officials say early analysis indicate the liquid was likely human bodily fluid.
"There is still no lead as to its source; authorities are presently not informed of any physical harm in association with the event," they added.
City officials stated they were working "to solve the incident" and have appealed to the residents for tips.
A senior representative said the incident made him speechless and had to be resolved rapidly.
"This event affects the center of Hanau and revives the pain of the extremist terrorist attack half a decade ago," he posted on social media, mentioning the murder of nine people by a assailant focusing on residents of foreign heritage in 2020.
