Roughly fifty cars have been smeared with what appears to be human blood in the German town of Hanau near Frankfurt, as reported by police.
Cars, walls and mailboxes were vandalized, in some cases with prohibited symbols, they stated in a statement.
Police say they were contacted late on Wednesday, when a resident observed that a vehicle in the Lamboy district of Hanau had been marked with a reddish-hued fluid.
The liquid had been placed in the shape of a swastika, they added.
Police then located numerous other vandalized cars and house walls in the surrounding area.
These symbols are illegal in Germany under laws banning the public exhibition of Nazi-era symbols.
Police state early analysis show the substance was probably human bodily fluid.
"At present there remains no lead as to where it came from; authorities are currently not aware of any injuries in connection with the incident," they stated.
City officials announced they were trying "to resolve the mystery" and have appealed to the public for tips.
An important representative commented the attack left him stunned and had to be solved rapidly.
"This event affects the very heart of Hanau and revives the trauma of the right-wing attack five years ago," he wrote on online, referring to the death of nine victims by a gunman aiming at people of foreign heritage in five years prior.
