Area Police
Around fifty vehicles have been covered with what appears to be human blood in the Germany's town of Hanau in proximity to Frankfurt, according to police.
Cars, building surfaces and postboxes were marked, in some cases with Nazi symbols, they stated in a release.
Police say they were contacted during the night on Wednesday night, when a resident discovered that a car in the Lamboy district of Hanau had been covered with a reddish fluid.
The liquid had been placed in the pattern of a swastika, they stated.
Law enforcement then found many other smeared vehicles and residential walls in the surrounding area.
Swastikas are banned in Germany under legislation prohibiting the public display of symbols from the Nazi era.
Police state early analysis show the substance was probably blood from a person.
"There is still no lead as to its origin; investigators are presently not cognizant of any injuries in association with the occurrence," they commented.
City officials announced they were working "to resolve the mystery" and have asked to the community for tips.
A senior political figure said the attack rendered him stunned and had to be resolved promptly.
"This event hits the core of Hanau and reawakens the wounds of the right-wing terrorist attack half a decade ago," he wrote on social media, mentioning the killing of nine victims by a shooter focusing on people of migrant background in five years prior.
