Around 50 vehicles have been smeared with what appears to be human blood in the Germany's town of Hanau close to Frankfurt, as reported by law enforcement.
Cars, exterior walls and postboxes were defaced, occasionally with Nazi symbols, they reported in a official communication.
Police say they were alerted during the night on Wednesday evening, when a individual discovered that a vehicle in the Lamboy neighborhood of Hanau had been covered with a red-colored liquid.
The substance had been applied in the form of a swastika, they reported.
Police then located many other vandalized vehicles and house walls in the nearby vicinity.
Swastikas are illegal in Germany under laws banning the public exhibition of symbols from the Nazi era.
Officials report preliminary tests suggest the liquid was probably human blood.
"There is still no lead as to its origin; authorities are presently not informed of any injuries in association with the incident," they added.
Municipal representatives said they were trying "to unravel the mystery" and have requested to the public for information.
An important political figure commented the vandalism rendered him stunned and had to be resolved promptly.
"This act affects the core of Hanau and reopens the wounds of the extremist attack in 2020," he wrote on online, mentioning the killing of nine victims by a assailant aiming at individuals of foreign heritage in February 2020.
