About 60 staff at a Tokyo zoo chased around a keeper dressed as a zebra on Friday in a drill to simulate one of the park’s animal inhabitants making a break for freedom.
The drill saw the zookeeper tackled and mock stun-gunned by his colleagues.
Visitors to the Tama Zoological Park were evacuated for the drill, which also supposed that one of the keepers had been severely injured when attempting to catch the escaped animal with a giant net.
The premise of the escape was that an earthquake — a regular occurrence in seismically-active Japan — destroyed a stone wall surrounding the animal’s enclosure.
Past simulations at the zoo have included escapes of lions, gorillas and tigers.
