Russian tennis player Yana Sizikova has been arrested as part of an investigation into match-fixing at last year's French Open, reports BBC News.
The 26-year-old doubles specialist was detained on Thursday at this year's tournament and is in custody in Paris.
Sizikova, who is ranked 101st in doubles, is yet to comment.
The investigation into alleged match-fixing was launched 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.
It 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.
Sizikova's hotel room was also searched, according to the Le Parisien newspaper which first reported her arrest.
