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.
A short training programme was developed which put an end to their interest and the monkeys are once again roaming their environment in a more natural state of play...
Staff at the zoo used old mobile phones that some of the keepers donated and put sticky substances on them that squirrel monkeys don't like.
