Area Police
Roughly 50 automobiles have been marked with what seems to be human bodily fluid in the Germany's town of Hanau near Frankfurt, as reported by police.
Vehicles, walls and mailboxes were vandalized, sometimes with swastikas, they announced in a release.
Officers say they were notified during the night on Wednesday evening, when a resident noticed that a vehicle in the Lamboy district of Hanau had been smeared with a reddish fluid.
The liquid had been drawn in the form of a swastika, they reported.
Officers then located many other vandalized vehicles and house walls in the surrounding area.
These symbols are illegal in Germany under laws banning the public exhibition of Nazi-era symbols.
Police report preliminary tests show the fluid was most likely human bodily fluid.
"Currently there is no lead as to its origin; investigators are presently not aware of any harm in association with the incident," they added.
City officials said they were working "to resolve the mystery" and have asked to the residents for details.
A senior representative stated the incident made him without words and had to be solved promptly.
"This event strikes at the very heart of Hanau and revives the trauma of the far-right violent incident five years ago," he stated on a platform, mentioning the death of nine people by a assailant focusing on residents of foreign heritage in five years prior.
