Local Police
Approximately 50 cars have been covered with what appears to be human bodily fluid in the Germany's town of Hanau near Frankfurt, according to authorities.
Cars, building surfaces and postal boxes were vandalized, in some cases with Nazi symbols, they announced in a official communication.
Law enforcement report they were notified in the late hours on Wednesday night, when a resident observed that a car in the Lamboy area of Hanau had been covered with a red-colored fluid.
The liquid had been applied in the form of a Nazi symbol, they added.
Police then discovered many other vandalized cars and residential walls in the surrounding area.
Swastikas are prohibited in Germany under laws outlawing the public display of Nazi symbols.
Officials say preliminary tests indicate the substance was most likely human bodily fluid.
"There is still no clue as to its source; officials are presently not cognizant of any harm in connection with the event," they added.
Local authorities said they were trying "to resolve the incident" and have appealed to the residents for details.
An important representative commented the incident rendered him stunned and required to be resolved rapidly.
"This event affects the very heart of Hanau and reawakens the wounds of the far-right attack in 2020," he posted on online, referring to the death of nine victims by a gunman aiming at residents of foreign heritage in February 2020.
