Zookeepers capture an escaped zebra at Ueno Zoo during an annual Escaped Animal Drill on February 2, 2016, Tokyo, Japan. Every year zookeepers at one of Tokyo's zoos organise an escape drill to practice what they would need to do in the event of a natural disaster or other emergency. This year a member of the zoo staff wearing a zebra costume "escaped" and was subsequently captured and subdued by other zookeepers before it could get out onto the streets of Tokyo. In past years, gorillas and rhinos have also been involved in these events which are in themselves a tourist attraction. The zoo workers used giant nets, sticks and tranquilizer guns to make sure the zebra didn't get away. (Video by Rodrigo Reyes Marin/NipponNews.net)
