A male zebra escaped a zoo in Seoul, South Korea and spent hours trotting through the city on busy roads and back alleys. Eventually, experts tranquilized the animal and returned it to the zoo. Social media videos showed the 3-year-old zebra, named Sero, galloping through the Gwangjin district of Seoul amid heavy traffic. Firefighters were dispatched to the scene and were able to herd it into an alley, where it was tranquilized and brought back to the Children’s Grand Park, where it normally resides in east Seoul.
