Local Police
Approximately 50 vehicles have been covered with what appears to be blood from a person in the German city of Hanau in proximity to Frankfurt, according to law enforcement.
Cars, building surfaces and mailboxes were marked, sometimes with Nazi symbols, they announced in a official communication.
Police state they were alerted late on Wednesday, when a man discovered that a car in the Lamboy neighborhood of Hanau had been covered with a reddish-hued substance.
The liquid had been drawn in the form of a banned symbol, they added.
Police then discovered many other marked automobiles and house walls in the surrounding area.
Swastikas are prohibited in Germany under legislation outlawing the public display of Nazi symbols.
Officials state preliminary tests suggest the liquid was probably human bodily fluid.
"There is still no clue as to its origin; officials are currently not informed of any harm in connection with the event," they added.
Municipal representatives said they were trying "to unravel the case" and have asked to the community for details.
A high-ranking official said the attack left him speechless and needed to be solved promptly.
"This incident affects the core of Hanau and reawakens the pain of the right-wing attack in 2020," he wrote on a platform, referring to the death of nine people by a shooter focusing on residents of migrant background in February 2020.
