IOC to investigate Chinese gold-medal gymnasts

The International Olympic Committee (IOC) has instigated an investigation into the ages of several Chinese gold-medal-winning gymnasts.



China is being asked to hand over extra documents to confirm that five gymnasts were old enough to compete.



For several months, there have been rumours about the ages of a number of Chinese gymnasts.



The International Gymnastics Federation confirmed it was looking into the cases of Miss He, Yang Yilin, Jiang Yuyuan, Li Shanshan and Deng Linlin.



All five were awarded gold medals at this Olympics, as part of the Chinese female squad that won the women\'s team event.
