Area Police
Approximately fifty vehicles have been smeared with what seems to be human blood in the Germany's city of Hanau close to Frankfurt, police confirm police.
Vehicles, walls and postal boxes were defaced, occasionally with swastikas, they announced in a release.
Officers say they were alerted in the late hours on Wednesday, when a resident discovered that a automobile in the Lamboy area of Hanau had been marked with a red-colored substance.
The liquid had been drawn in the shape of a swastika, they added.
Police then discovered multiple other smeared vehicles and residential walls in the nearby vicinity.
Nazi symbols are illegal in Germany under legislation outlawing the visible presentation of Nazi-era symbols.
Law enforcement say preliminary tests show the liquid was likely human bodily fluid.
"At present there remains no lead as to its source; officials are presently not aware of any injuries in connection with the incident," they stated.
City officials said they were attempting "to unravel the incident" and have appealed to the community for details.
A senior political figure stated the attack made him stunned and needed to be addressed rapidly.
"This act strikes at the center of Hanau and reawakens the trauma of the right-wing terrorist attack half a decade ago," he posted on social media, mentioning the murder of nine people by a shooter targeting residents of foreign heritage in five years prior.
