A russian was detained in Paris for trying to "destabilize" the Olympics, - CNN

French authorities searched the man's residence, where they found evidence suggesting he was preparing "events that could lead to destabilization during the Olympic Games." The prosecutor's office does not provide more details about what the man allegedly planned.

A preliminary investigation was launched against him. He was detained yesterday on suspicion of "intelligence activities with a foreign state with the aim of provoking military actions in France."

If convicted, the maximum penalty for the crime is 30 years in prison.

Last week, the French Interior Ministry said that around 4,000 people had been refused entry to the Olympics, with a particular focus on citizens of Russia and Belarus.

The official opening ceremony of the Olympic Games will take place this Friday evening in the center of Paris.
