A Taiwanese Taekwondo fighter was disqualified from the Asian games after it was found she was hiding extra sensors in her socks.
Yang Shu-Chun was ousted before a quarter-final match against Vietnamese representative Vu Thi Hau.
Along with her coach, the athlete was further reprimanded for refusing to leave the contest area where they were protesting against the disqualification.
Although athletes are allowed to wear authorised socks which have sensors built in, 2008 Olympic medallist was found to have an extra sensor taped to each of her heels.
Extra sensors could reportedly help fighters score extra points under a new electronic scoring system.
The AFP reports that the secretary general of the World Taekwondo Federation Yang Jin-Suk was shocked by the incident.
"When somebody tries to take advantage by manipulating equipment to gain more points, it is unfair," he said.Browse Christmas Socks... Step Out with Funky, Festive Feet
