Area Police
Around 50 vehicles have been marked with what seems to be human blood in the Germany's municipality of Hanau in proximity to Frankfurt, as reported by authorities.
Cars, walls and postal boxes were defaced, occasionally with Nazi symbols, they reported in a statement.
Police report they were notified late on Wednesday evening, when a man observed that a car in the Lamboy area of Hanau had been smeared with a reddish-hued fluid.
The fluid had been drawn in the pattern of a banned symbol, they reported.
Police then discovered many other vandalized automobiles and residential walls in the surrounding area.
Nazi symbols are illegal in Germany under regulations banning the public display of Nazi-era symbols.
Police say early analysis indicate the liquid was likely blood from a person.
"At present there remains no clue as to where it came from; authorities are currently not cognizant of any injuries in association with the occurrence," they commented.
Local authorities announced they were attempting "to solve the incident" and have asked to the public for tips.
An important official stated the attack made him without words and needed to be resolved promptly.
"This incident affects the very heart of Hanau and reopens the trauma of the right-wing violent incident half a decade ago," he stated on online, referring to the murder of nine victims by a assailant targeting residents of foreign heritage in five years prior.
