INTERNATIONAL: Russian figure skating sensation Kamila Valieva has showed up for her scheduled practice at the Beijing Olympics on Thursday after media has reported the 15-year-old had tested positive for a banned substance.

The teenager was part of the Russian Olympic Committee (ROC) ensemble that won the figure skating team event on Monday, ahead of the United States and Japan. The ceremony to present her and her team mates with their Olympic medals has been delayed since then for unexplained legal reasons.

Despite the pressure surrounding her, the teenager has performed quadruple jumps in practice, after becoming the first woman to complete a quad jump at an Olympics during her teams winning performance on Monday.

Valieva has declined to answer questions in the mixed zone, the area where journalists interview athletes after competition.

There was a report on Wednesday that Valieva had returned a positive test, naming the drug as Trimetazidine, which is typically used to treat chest pain.

Repeated attempts to reach the ROC chef de mission by Reuters were unsuccessful. His phone was not answering, and the ROC office in Beijing was locked and unmanned on Thursday. The ROC on Wednesday has declined to comment on the reports that Valieva had returned a positive test.

In a press conference on Thursday, the International Olympics Committee has repeatedly refused to answer questions, citing concerns about legal process.
