Tokyo Olympics: Volleyball player claims innocence over positive drug test

Rio De Janeiro - Brazil's Tandara Caixeta flew home after she was suspended for doping.

A Brazilian volleyball player suspended for doping while competing in the Tokyo Olympics has claimed the banned substance found in a July test was introduced accidentally into her system.

In a letter released by her lawyer on Friday, Tandara Caixeta, who has left the team's camp and flown home to Brazil, did not explain further but said she had not knowingly taken Ostarina, a drug used by bodybuilders and to improve athletic performance.

"We fully trust that we will prove Ostarina entered accidentally into the athlete's organism and that it was not used to enhance sporting performance," said the lawyer's letter.

The positive test was taken out of competition at the Brazilian volleyball training centre on July 7, the committee said.
