A Russian man has been arrested in France on suspicion of plotting acts of "destabilisation" during the Paris Olympics, prosecutors have said, reports the BBC.
Local media reports that a 40-year-old man was arrested on Sunday and an investigation opened into the possible passing of "intelligence to a foreign power in order to arouse hostilities in France".
The alleged plot is not believed to have been for a terror attack.
It comes just days before the games get under way, with the opening ceremony set to take place in central Paris on Friday.
Prosecutors said a search had been carried out at the man's Paris apartment at the request of the French interior ministry.
A source close to the investigation told Le Parisien, external agents had discovered evidence that suggested the man was preparing "pro-Russian operations" to destabilise France during the games.
Another source said the alleged plot was a "large-scale project" that could have had "serious" consequences.
