Sports 2012 images: Olympic controversies

China's Ye Shiwen holds her gold medal after winning the women's 200m individual medley final at the London 2012 Summer Olympics on July 31, 2012. The 16-year-old won both of the 200m and 400m women's individual medley gold, edging the 400m world record and breaking the 200m Olympic record twice. The Olympic newcomer, who was timed faster than her male counterpart gold winner Ryan Lochte of the US, was bombarded with questions from the foreign media falsely linking her win to drug use.
