Local Police
Approximately 50 cars have been marked with what seems to be blood from a person in the Germany's municipality of Hanau close to Frankfurt, according to law enforcement.
Cars, exterior walls and mailboxes were marked, sometimes with prohibited symbols, they announced in a release.
Law enforcement say they were contacted during the night on Wednesday evening, when a resident observed that a car in the Lamboy neighborhood of Hanau had been covered with a red-colored substance.
The substance had been placed in the pattern of a swastika, they reported.
Law enforcement then discovered many other vandalized automobiles and building exteriors in the surrounding area.
Swastikas are banned in Germany under legislation banning the public exhibition of Nazi-era symbols.
Police state preliminary tests indicate the fluid was probably blood from a person.
"At present there remains no lead as to where it came from; authorities are presently not aware of any physical harm in connection with the incident," they added.
City officials announced they were attempting "to resolve the mystery" and have appealed to the community for information.
A high-ranking official stated the attack made him without words and had to be addressed quickly.
"This event hits the core of Hanau and reopens the wounds of the far-right terrorist attack in 2020," he posted on social media, mentioning the murder of nine individuals by a shooter targeting residents of foreign heritage in five years prior.
