Around 50 cars have been covered with what appears to be human bodily fluid in the German city of Hanau close to Frankfurt, as reported by authorities.
Vehicles, walls and postboxes were marked, occasionally with swastikas, they announced in a statement.
Police say they were notified late on Wednesday, when a individual noticed that a automobile in the Lamboy district of Hanau had been marked with a red-colored liquid.
The substance had been placed in the form of a swastika, they added.
Officers then located many other vandalized vehicles and house walls in the adjacent neighborhood.
Swastikas are illegal in Germany under laws banning the public exhibition of Nazi-era symbols.
Police state preliminary tests show the fluid was probably human blood.
"Currently there is no clue as to its origin; authorities are presently not aware of any injuries in connection with the event," they commented.
City officials said they were trying "to solve the mystery" and have appealed to the residents for information.
An important political figure said the vandalism made him without words and had to be addressed rapidly.
"This incident hits the very heart of Hanau and reopens the trauma of the right-wing attack five years ago," he posted on online, mentioning the murder of nine individuals by a gunman aiming at individuals of immigrant origin in five years prior.
