Police are searching the forests and neighborhoods around Berlin for an escaped lioness. The stay-at-home warning went out after video was shared on social media, reportedly showing the big cat chasing a wild boar. About 100 police officers, animal care specialists and hunters are searching for the lioness using two helicopters, drones and infrared cameras. Authorities say they plan to tranquilize and capture the predator, unless she poses a threat to human life.
