Local Police
Approximately fifty vehicles have been covered with what appears to be blood from a person in the Germany's city of Hanau near Frankfurt, according to police.
Cars, exterior walls and postal boxes were defaced, in some cases with swastikas, they stated in a statement.
Law enforcement report they were contacted in the late hours on Wednesday night, when a resident discovered that a car in the Lamboy area of Hanau had been smeared with a reddish-hued substance.
The substance had been applied in the pattern of a Nazi symbol, they reported.
Officers then located multiple other smeared automobiles and residential walls in the surrounding area.
Nazi symbols are illegal in Germany under regulations banning the public exhibition of symbols from the Nazi era.
Police say initial examinations suggest the substance was probably human blood.
"Currently there is no lead as to its source; investigators are currently not aware of any harm in relation with the event," they added.
Local authorities announced they were trying "to unravel the mystery" and have asked to the public for tips.
A senior official stated the attack rendered him without words and needed to be resolved rapidly.
"This act affects the very heart of Hanau and reawakens the wounds of the far-right terrorist attack in 2020," he wrote on social media, mentioning the death of nine individuals by a gunman targeting residents of immigrant origin in February 2020.
