Local Police
Approximately 50 vehicles have been covered with what seems to be human blood in the German city of Hanau close to Frankfurt, police confirm law enforcement.
Automobiles, walls and postal boxes were vandalized, occasionally with Nazi symbols, they stated in a statement.
Law enforcement say they were notified late on Wednesday, when a resident observed that a automobile in the Lamboy district of Hanau had been marked with a reddish liquid.
The fluid had been placed in the pattern of a banned symbol, they reported.
Officers then located multiple other vandalized cars and residential walls in the surrounding area.
Swastikas are prohibited in Germany under legislation prohibiting the public display of Nazi symbols.
Law enforcement say early analysis suggest the fluid was most likely blood from a person.
"There is still no clue as to its origin; officials are presently not informed of any injuries in association with the incident," they added.
Municipal representatives said they were trying "to unravel the mystery" and have requested to the residents for details.
An important official commented the attack rendered him stunned and had to be addressed rapidly.
"This incident strikes at the very heart of Hanau and revives the wounds of the right-wing violent incident five years ago," he posted on online, mentioning the murder of nine individuals by a shooter targeting residents of immigrant origin in five years prior.
