Local Police
Approximately 50 vehicles have been covered with what seems to be human blood in the Germany's municipality of Hanau in proximity to Frankfurt, as reported by law enforcement.
Vehicles, exterior walls and postal boxes were marked, sometimes with prohibited symbols, they reported in a official communication.
Police say they were notified in the late hours on Wednesday evening, when a resident noticed that a car in the Lamboy neighborhood of Hanau had been smeared with a reddish fluid.
The substance had been placed in the form of a Nazi symbol, they reported.
Officers then located many other smeared cars and residential walls in the adjacent neighborhood.
Swastikas are prohibited in Germany under legislation banning the public display of symbols from the Nazi era.
Police say initial examinations show the liquid was most likely blood from a person.
"There is still no clue as to its source; investigators are presently not aware of any injuries in connection with the incident," they commented.
Municipal representatives announced they were attempting "to solve the mystery" and have appealed to the community for information.
A high-ranking official stated the incident made him speechless and required to be resolved rapidly.
"This incident strikes at the core of Hanau and revives the pain of the right-wing terrorist attack five years ago," he stated on online, recalling the murder of nine people by a assailant focusing on residents of foreign heritage in five years prior.
