Russian tennis player Yana Sizikova has been released from police custody a day after she was arrested as part of an investigation into match-fixing at last year's French Open.
The 26-year-old, who is ranked 101st in doubles, was released without being charged.
She is "shocked" at the allegations, her lawyer told Russia's Tass news.
The investigation began in October after suspicions of "organised fraud" and "sports corruption" were raised.
At the time, a source close to the investigation told the BBC the inquiry was examining several players including Sizikova.
The investigation was announced shortly after Sizikova and the American player Madison Brengle lost to the Romanians Andreea Mitu and Patricia Maria Tigin in the tournament's opening round.
Suspicions were reportedly raised after betting companies noticed hundreds of thousands of euros had been wagered on a break of serve in the second set.
Despire Sizikova's release on Friday, the investigation is continuing.
"Yana Sizikova is shocked and rejects charges of crimes she has never committed... these accusations harm her reputation," her lawyer Frederic Belo told the Tass news agency, adding that she intends to file a complaint for libel.
Mr Belo said he was not sure if Ms Sizikova would be allowed to leave France, explaining that she was "accused of sporting corruption, which is punishable by five years in prison and a 500,000 euro ($608,000; £430,000) fine.
"She is also suspected of fraud as part of an organised group. Under this article, she could face up to five years in prison and a fine of 300,000 euros ($365,000; £260,000)," Mr Belo said.
