Local Police
Roughly 50 cars have been marked with what seems to be human blood in the Germany's city of Hanau in proximity to Frankfurt, according to police.
Cars, building surfaces and postboxes were defaced, in some cases with Nazi symbols, they reported in a statement.
Law enforcement say they were contacted during the night on Wednesday, when a individual discovered that a car in the Lamboy neighborhood of Hanau had been marked with a red-colored substance.
The substance had been applied in the form of a swastika, they reported.
Police then found numerous other marked vehicles and residential walls in the adjacent neighborhood.
Nazi symbols are banned in Germany under laws outlawing the public exhibition of Nazi-era symbols.
Officials report early analysis show the liquid was probably blood from a person.
"Currently there is no lead as to its origin; officials are not yet informed of any injuries in association with the incident," they commented.
Municipal representatives announced they were working "to solve the incident" and have appealed to the community for details.
A senior representative said the attack made him stunned and had to be addressed rapidly.
"This incident strikes at the center of Hanau and reopens the trauma of the right-wing attack half a decade ago," he wrote on a platform, mentioning the murder of nine victims by a assailant targeting people of foreign heritage in five years prior.
