Area Police
Around 50 cars have been covered with what seems to be blood from a person in the German town of Hanau close to Frankfurt, police confirm authorities.
Automobiles, walls and postboxes were vandalized, occasionally with swastikas, they reported in a statement.
Law enforcement report they were alerted late on Wednesday evening, when a resident noticed that a automobile in the Lamboy area of Hanau had been marked with a reddish-hued fluid.
The liquid had been applied in the pattern of a banned symbol, they added.
Officers then discovered multiple other smeared cars and building exteriors in the surrounding area.
Nazi symbols are prohibited in Germany under laws prohibiting the public exhibition of symbols from the Nazi era.
Law enforcement say early analysis show the liquid was likely human blood.
"There is still no clue as to where it came from; investigators are presently not cognizant of any harm in association with the occurrence," they added.
Local authorities stated they were attempting "to solve the incident" and have appealed to the residents for tips.
A senior official stated the vandalism rendered him without words and had to be resolved rapidly.
"This act strikes at the center of Hanau and reopens the trauma of the far-right terrorist attack five years ago," he stated on social media, recalling the death of nine people by a shooter focusing on residents of foreign heritage in five years prior.
