Japanese zoo stages 'gorilla escape'

Staff at a Japanese zoo chased a keeper in a gorilla costume as part of their annual escape drill.

It's all to help the keepers brush up on their skills in case a real gorilla broke out.

Zookeeper Natsumi Uno, who was inside the gorilla suit, said it had been nice to be able to switch places for the day.

She said: "When the other keepers chased me, I could really understand the animal's feelings. We need to think about people's safety, but also about the safety of the animal we are catching. That is why this drill is important."
