October 14 - Belgium's Charline Van Snick, a London 2012 bronze medallist, has tested positive for cocaine at this year's World Judo Championships, she has announced.
The 23-year-old from Liège, who also won a bronze at the World Championships in Rio de Janeiro in August, beating Argentinian Paula Pareto, revealed the news during an interview with Belgian public radio station RTBF.
"I received a letter informing me that a banned substance had been found in one of my urine samples, metabolites of cocaine," said Van Snick, who also won a silver medal at this year's European Championships in Budapest.
"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."
Van Snick faces a two-year suspension and the loss of her medal in the under 48 kilogram category from Rio is now awaiting the results of the B sample.
"With my lawyer, we are building a case to prove my innocence," she said.
"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."
