Roughly 50 automobiles have been marked with what seems to be human bodily fluid in the German municipality of Hanau in proximity to Frankfurt, according to police.
Cars, building surfaces and postal boxes were defaced, sometimes with swastikas, they announced in a release.
Law enforcement state they were alerted late on Wednesday evening, when a resident discovered that a car in the Lamboy neighborhood of Hanau had been covered with a red-colored liquid.
The liquid had been placed in the pattern of a Nazi symbol, they added.
Police then discovered many other vandalized vehicles and residential walls in the surrounding area.
Swastikas are banned in Germany under legislation outlawing the public display of Nazi symbols.
Law enforcement say initial examinations indicate the substance was most likely human blood.
"At present there remains no lead as to its source; officials are presently not aware of any harm in association with the occurrence," they added.
Municipal representatives stated they were trying "to solve the mystery" and have appealed to the public for details.
An important official commented the attack left him speechless and needed to be solved quickly.
"This incident strikes at the center of Hanau and revives the trauma of the extremist terrorist attack five years ago," he wrote on a platform, recalling the killing of nine victims by a assailant targeting people of foreign heritage in five years prior.
