Two lions broke free from their cage in a zoo to the south of Berlin on Wednesday, according to a police report.
There were some 100 people in the zoo in the town of Baruth at the time of the incident, but they were all evacuated to safety.
A lioness managed to escape from her enclosure into the area in front of it where she fretfully ran up and down.
A second animal, a lion, only made it as far as a secured neighbouring enclosure.
After two hours a female vet was able to tranquilize the lioness.
Police said people were not in danger at any point.
