A troop of mischievous monkeys at London Zoo have had to be re-trained after showing too much interest in mobile phones. The ring tones and bright lights proved just too attractive to the squirrel monkeys in their new no-barrier enclosure. Visitors who held out their phones to video or take photographs attracted attention from the monkeys who attempted to take the object. . .Malcolm Fitzpatrick, curator of mammals at the Zoological Society of London, said: “The new barrier free enclosure means the monkeys are in closer proximity to visitors.

Barrier free enclosure? This does not sound like a good idea to me.
