Alexei Navalny, a critic of the Russian government who was poisoned with a nerve agent last year, has been sentenced to 30 days in jail.
At the hearing on Monday, prosecutors said he had violated the parole terms of a suspended sentence for embezzlement.
The Russian opposition figure, 44, had been arrested on Sunday upon arrival at a Moscow airport.
Russia's prison service said last week that Navalny, who blamed his poisoning on the Kremlin, faces immediate arrest once he returns. Russia's government has repeatedly denied a role in the poisoning.
