Judicial officials have told The Associated Press that the Russian tennis player arrested on suspicion of match-fixing at last year's French Open has been released from police custody.

PARIS – The Paris prosecutor’s office has opened a police investigation into suspicions of match-fixing at the French Open. The Paris prosecutor’s office said the investigation is centered on suspicions concerning one match at Roland Garros and also casting a broader look for any other evidence. German newspaper Die Welt and French sports daily L’Equipe said there were suspicious betting patterns in the first round of a women’s doubles match on Sept. 30. The prosecutor’s office said probe was opened on Oct. 1, the day after. The French tennis federation, which runs the French Open, referred all questions to the Tennis Integrity Unit, which oversees corruption investigations in the sport.
