Local Law Enforcement
Approximately fifty cars have been marked with what appears to be human blood in the Germany's municipality of Hanau close to Frankfurt, according to authorities.
Cars, building surfaces and postal boxes were defaced, in some cases with prohibited symbols, they reported in a release.
Law enforcement state they were notified during the night on Wednesday evening, when a resident observed that a car in the Lamboy district of Hanau had been smeared with a reddish substance.
The substance had been placed in the form of a swastika, they added.
Officers then located numerous other smeared vehicles and house walls in the adjacent neighborhood.
Nazi symbols are banned in Germany under regulations outlawing the public exhibition of Nazi symbols.
Law enforcement report early analysis show the substance was likely blood from a person.
"At present there remains no lead as to its origin; authorities are not yet cognizant of any physical harm in association with the occurrence," they stated.
Local authorities announced they were trying "to unravel the case" and have appealed to the public for details.
An important official said the vandalism rendered him without words and required to be resolved quickly.
"This event affects the center of Hanau and reawakens the pain of the extremist attack half a decade ago," he wrote on a platform, mentioning the murder of nine people by a assailant aiming at residents of immigrant origin in five years prior.
