Police are searching for an animal they believe is a lioness in the south-western outskirts of Berlin.
A police spokeswoman said they received calls and a video alerting them to the wild animal at about midnight on Wednesday, and immediately began their search.
At least 30 police cars were deployed, and veterinarians called to assist in the search for the big cat.
Residents have being told to stay indoors until it is found.
A video shared on Twitter – which police believe is real – also appeared to show a lioness in a heavily forested residential area of Kleinmachnow.
However, it is unclear where the animal came from.
Local zoos, animal sanctuaries and circuses said no lions have escaped from their facilities.
Residents have been advised to stay indoors and keep their pets with them.
Helicopters have been deployed to find the elusive animal as well as drones and heat-seeking cameras.
Veterinarians and hunters with tranquilize guns are also involved in the search, while local media reported that police were using an armored vehicle normally deployed in anti-terrorist operations
