The storm had caused widespread devastation in the region, where many residents were Friday clearing muddy water from their cellars and removing downed trees.
In an earlier zoo incident two year ago, two lions broke out of their cages at the Leipzig zoo. One was shot dead and the other was forced back into its cage, according to the BBC.
In the end, a drone sighted the remaining escapees inside the zoo compound.
