Belgian judoka Charline van Snick, a bronze medal winner from the 2012 London Olympic Games, revealed Monday that she returned a positive test for cocaine during the world championships in Rio in August where she also won bronze.

"I received a letter informing me that a banned substance had been found in one of my urine samples, metabolites of cocaine," Van Snick told reporters.

"The news stunned me, because I am very careful with this, and I really have a perfect lifestyle. I have never taken any substance that can improve my performance. Not intentionally anyway."

The 23-year-old, who faces a two-year suspension and the loss of her medal in the lightweight category from Rio, is now awaiting the results of the B sample.

"With my lawyer, we are building a case to prove my innocence. I've always tried to be as professional as possible and meet all my doping obligations and I don't understand how such a thing could have happened," she said.
