Roughly fifty vehicles have been covered with what seems to be human blood in the Germany's city of Hanau close to Frankfurt, as reported by authorities.
Vehicles, walls and mailboxes were marked, in some cases with prohibited symbols, they stated in a official communication.
Police state they were contacted during the night on Wednesday, when a individual noticed that a automobile in the Lamboy neighborhood of Hanau had been marked with a red-colored substance.
The liquid had been applied in the form of a banned symbol, they reported.
Law enforcement then found many other smeared cars and house walls in the adjacent neighborhood.
Swastikas are prohibited in Germany under legislation banning the public exhibition of Nazi-era symbols.
Officials state preliminary tests suggest the substance was probably blood from a person.
"At present there remains no indication as to its origin; investigators are currently not cognizant of any harm in relation with the event," they added.
Local authorities said they were trying "to resolve the mystery" and have appealed to the residents for details.
A high-ranking political figure stated the attack left him speechless and required to be solved promptly.
"This event hits the very heart of Hanau and revives the pain of the extremist attack in 2020," he wrote on online, mentioning the killing of nine individuals by a gunman aiming at individuals of migrant background in five years prior.
