Staff at a Japanese zoo have been practising procedures designed to recapture escaped animals in the event of an earthquake.
An employee of Tama Zoo outside Tokyo donned a zebra costume during the drill as emergency workers set up a barricade.
Carrie Gracie describes how the scenario culminated in the 'zebra' being tranquilised.
