Area Police
Approximately fifty vehicles have been covered with what appears to be blood from a person in the Germany's municipality of Hanau in proximity to Frankfurt, according to police.
Vehicles, exterior walls and postal boxes were defaced, in some cases with swastikas, they announced in a statement.
Law enforcement state they were notified during the night on Wednesday, when a man observed that a car in the Lamboy district of Hanau had been covered with a reddish fluid.
The liquid had been drawn in the form of a swastika, they added.
Police then located many other vandalized vehicles and residential walls in the nearby vicinity.
Nazi symbols are illegal in Germany under legislation banning the public display of Nazi-era symbols.
Police state initial examinations suggest the fluid was likely human blood.
"Currently there is no clue as to its origin; officials are currently not informed of any injuries in connection with the event," they added.
Local authorities said they were attempting "to unravel the case" and have requested to the public for tips.
A senior representative commented the incident rendered him stunned and required to be resolved quickly.
"This incident hits the center of Hanau and revives the wounds of the right-wing terrorist attack five years ago," he wrote on online, mentioning the murder of nine victims by a assailant aiming at individuals of foreign heritage in 2020.
