Area Police
Approximately 50 vehicles have been marked with what appears to be human blood in the German municipality of Hanau near Frankfurt, as reported by police.
Vehicles, building surfaces and mailboxes were defaced, sometimes with swastikas, they announced in a statement.
Officers report they were alerted late on Wednesday night, when a man discovered that a vehicle in the Lamboy neighborhood of Hanau had been marked with a red-colored substance.
The fluid had been drawn in the pattern of a swastika, they reported.
Officers then found numerous other vandalized cars and house walls in the adjacent neighborhood.
Nazi symbols are banned in Germany under legislation outlawing the visible presentation of Nazi symbols.
Officials report initial examinations indicate the liquid was most likely human bodily fluid.
"There is still no lead as to where it came from; authorities are presently not aware of any harm in relation with the occurrence," they added.
Local authorities said they were working "to solve the mystery" and have appealed to the public for information.
A high-ranking political figure stated the incident rendered him speechless and had to be resolved rapidly.
"This incident affects the core of Hanau and revives the wounds of the extremist violent incident half a decade ago," he wrote on online, mentioning the death of nine people by a gunman aiming at individuals of migrant background in February 2020.
