Roughly 50 cars have been covered with what seems to be human blood in the Germany's city of Hanau in proximity to Frankfurt, police confirm authorities.
Vehicles, walls and postal boxes were vandalized, occasionally with swastikas, they announced in a official communication.
Officers say they were contacted during the night on Wednesday night, when a man discovered that a car in the Lamboy district of Hanau had been marked with a red-colored liquid.
The substance had been drawn in the form of a Nazi symbol, they stated.
Law enforcement then discovered numerous other vandalized vehicles and house walls in the nearby vicinity.
Swastikas are prohibited in Germany under legislation outlawing the visible presentation of Nazi-era symbols.
Law enforcement state initial examinations suggest the liquid was probably human blood.
"There is still no lead as to its source; authorities are presently not aware of any physical harm in association with the event," they added.
City officials stated they were attempting "to unravel the incident" and have requested to the community for details.
A high-ranking official commented the attack made him stunned and needed to be resolved rapidly.
"This act affects the core of Hanau and reawakens the trauma of the far-right terrorist attack half a decade ago," he wrote on social media, recalling the murder of nine victims by a gunman aiming at individuals of migrant background in five years prior.
