Local Police
Around fifty vehicles have been covered with what appears to be human bodily fluid in the Germany's municipality of Hanau close to Frankfurt, according to authorities.
Cars, exterior walls and mailboxes were vandalized, occasionally with prohibited symbols, they announced in a official communication.
Officers report they were alerted during the night on Wednesday night, when a individual noticed that a vehicle in the Lamboy area of Hanau had been smeared with a reddish-hued liquid.
The substance had been placed in the shape of a banned symbol, they added.
Police then discovered many other vandalized cars and residential walls in the surrounding area.
Swastikas are banned in Germany under laws prohibiting the public exhibition of Nazi-era symbols.
Police state initial examinations show the fluid was likely blood from a person.
"Currently there is no lead as to its origin; authorities are not yet informed of any injuries in association with the occurrence," they commented.
Local authorities stated they were trying "to unravel the mystery" and have requested to the residents for information.
A senior official said the attack rendered him stunned and needed to be solved quickly.
"This act affects the center of Hanau and reawakens the wounds of the far-right terrorist attack half a decade ago," he posted on online, mentioning the death of nine victims by a assailant targeting individuals of migrant background in five years prior.
