Around fifty vehicles have been smeared with what appears to be human blood in the Germany's city of Hanau near Frankfurt, police confirm authorities.
Cars, building surfaces and mailboxes were vandalized, in some cases with Nazi symbols, they reported in a official communication.
Police say they were contacted during the night on Wednesday, when a resident discovered that a car in the Lamboy district of Hanau had been marked with a red-colored liquid.
The fluid had been placed in the form of a swastika, they added.
Police then located many other vandalized cars and building exteriors in the adjacent neighborhood.
Swastikas are prohibited in Germany under legislation prohibiting the public display of Nazi-era symbols.
Police state initial examinations indicate the substance was most likely blood from a person.
"Currently there is no indication as to its source; authorities are not yet aware of any injuries in connection with the occurrence," they commented.
Municipal representatives announced they were working "to unravel the incident" and have requested to the public for details.
A senior representative said the attack made him stunned and needed to be solved quickly.
"This event strikes at the very heart of Hanau and reawakens the trauma of the right-wing attack five years ago," he wrote on social media, mentioning the murder of nine individuals by a shooter focusing on people of immigrant origin in five years prior.
