Roughly 50 cars have been covered with what seems to be human bodily fluid in the German town of Hanau near Frankfurt, as reported by police.
Cars, walls and mailboxes were defaced, occasionally with swastikas, they announced in a official communication.
Officers report they were notified late on Wednesday night, when a resident noticed that a car in the Lamboy district of Hanau had been marked with a red-colored substance.
The fluid had been placed in the form of a Nazi symbol, they reported.
Officers then found many other marked cars and house walls in the adjacent neighborhood.
Swastikas are illegal in Germany under laws outlawing the public exhibition of Nazi symbols.
Police report preliminary tests show the liquid was most likely human blood.
"Currently there is no clue as to its origin; investigators are not yet informed of any physical harm in relation with the incident," they stated.
Local authorities announced they were trying "to unravel the mystery" and have asked to the public for tips.
An important representative said the vandalism left him without words and required to be solved rapidly.
"This incident affects the center of Hanau and revives the pain of the right-wing terrorist attack five years ago," he stated on a platform, mentioning the murder of nine people by a gunman aiming at people of migrant background in five years prior.
