Armed police were called to the central London attraction and visitors were evacuated as keepers tried to recapture the animal.
But Kumbuka wasn’t looking for any trouble. Apparently, it was looking for delicious fruity syrup.
Zoo staff managed then to contain Kumbuka in the staff-only corridor, which is where the primate partook of his fruity indulgence.
They tranquilized it and transported it back to its den.
The amount of concentrated syrup Kumbuka consumed could have potentially caused some serious digestive troubles.
