2012 Olympics: Artistic Gymnast Kicked Out of Games After Failing Drug Test

The International Olympic Committee says artistic gymnast Luiza Galiulina of Uzbekistan has been formally expelled from the London Olympics after tests on her B sample were positive.

Traces of a banned diuretic called "furosemide" were found in a urine sample.

The 20-year-old of Tashkent claimed that she has no idea how the substance entered her body. She told the committee she took medication for a heart condition July 22 and 23.
