The woman was visiting a zoo in Burundi when she let her guards down and the monkey pounced on her phone.
She got too close to the monkey in the zoo then she got a shock of her life when the mammal grabbed her phone and refused to give it back.
The monkey then dragged the phone against the iron bars of its enclosure as it jumped around.
When zoo staff finally got the phone from the monkey, it had done major damage to it.
The damaged phone was returned to the lady and she left with her male companion.
