Local Police
Around 50 vehicles have been marked with what seems to be human blood in the Germany's city of Hanau close to Frankfurt, according to police.
Automobiles, walls and mailboxes were defaced, in some cases with swastikas, they stated in a official communication.
Law enforcement state they were notified during the night on Wednesday evening, when a individual noticed that a car in the Lamboy area of Hanau had been smeared with a reddish substance.
The liquid had been placed in the shape of a swastika, they reported.
Officers then found numerous other marked cars and residential walls in the nearby vicinity.
Swastikas are prohibited in Germany under regulations outlawing the public display of Nazi-era symbols.
Officials state initial examinations suggest the substance was probably blood from a person.
"At present there remains no lead as to its source; authorities are not yet cognizant of any injuries in association with the event," they added.
City officials stated they were working "to unravel the incident" and have requested to the community for information.
An important official said the vandalism left him without words and needed to be resolved quickly.
"This event affects the center of Hanau and reopens the wounds of the far-right terrorist attack five years ago," he wrote on online, mentioning the murder of nine victims by a gunman aiming at people of foreign heritage in February 2020.
