Chinese girl's 'faster swim than Lochte' sparks controversy

Shiwen, who wasn't among the pre-race favourites, announced her arrival on swimming's greatest stage with a world record in the arduous 400m individual medley event. Shiwen's time of four minutes, 28.3 seconds beat the world record by more than a second and her previous best by five seconds. Her final length of 28.93 seconds even beat Ryan Lochte, who swam the last length in 29.1 seconds in his gold medal-winning race in the men's 400 individual medley. But, Foster downplayed any kind of possibility of foul play, and said such feats could be achieved. Balding's question attracted huge criticism on social networking site Twitter, with many branding her question as demeaning to the hard work done by the Chinese athletes.
