When Kumbuka, a silverback gorilla, got out his enclosure at London Zoo recently, he helped himself to five litres of blackcurrant squash.

A report has been published showing that the Gorilla escaped through an unlocked door and in to a secured keepers area. He was returned to his den about two hours later, after being tranquillized

Professor David Field, the zoological director at the zoo explained to 麻豆社 Radio 4's PM programme what Kumbuka did with his freedom.
