Roughly fifty vehicles have been covered with what appears to be blood from a person in the Germany's city of Hanau close to Frankfurt, according to law enforcement.
Cars, exterior walls and mailboxes were vandalized, occasionally with swastikas, they stated in a release.
Law enforcement state they were notified during the night on Wednesday, when a man observed that a vehicle in the Lamboy district of Hanau had been smeared with a reddish-hued liquid.
The fluid had been applied in the pattern of a banned symbol, they added.
Police then located multiple other smeared vehicles and house walls in the adjacent neighborhood.
Nazi symbols are illegal in Germany under legislation outlawing the visible presentation of Nazi symbols.
Officials state initial examinations suggest the substance was probably human bodily fluid.
"Currently there is no indication as to its origin; authorities are currently not informed of any harm in association with the event," they commented.
City officials said they were trying "to solve the mystery" and have appealed to the community for tips.
A senior official commented the incident left him stunned and needed to be solved rapidly.
"This act hits the center of Hanau and reawakens the pain of the far-right attack half a decade ago," he wrote on online, mentioning the murder of nine people by a gunman focusing on individuals of immigrant origin in five years prior.
