Area Police
Approximately fifty cars have been covered with what appears to be human bodily fluid in the German city of Hanau near Frankfurt, according to law enforcement.
Automobiles, building surfaces and postal boxes were marked, sometimes with swastikas, they announced in a official communication.
Police say they were notified in the late hours on Wednesday evening, when a resident discovered that a car in the Lamboy area of Hanau had been marked with a reddish substance.
The fluid had been applied in the form of a banned symbol, they reported.
Police then found many other marked automobiles and residential walls in the nearby vicinity.
Swastikas are banned in Germany under regulations banning the public exhibition of symbols from the Nazi era.
Officials state initial examinations show the liquid was probably human blood.
"At present there remains no clue as to its origin; officials are not yet cognizant of any physical harm in relation with the event," they commented.
City officials said they were working "to solve the mystery" and have appealed to the residents for tips.
An important political figure said the incident left him speechless and had to be resolved quickly.
"This event hits the very heart of Hanau and reopens the trauma of the right-wing terrorist attack five years ago," he wrote on a platform, recalling the death of nine people by a shooter focusing on residents of immigrant origin in five years prior.
