A Moscow court has sentenced an activist to three years and two months in prison over a May 2012 protest against President Vladimir Putin.
Dmitry Ishevsky was convicted of rioting and assaulting a police officer during the protest on the eve of Putin's inauguration to a third term.
More than 400 people were arrested after violence erupted at the protest on Moscow's Bolotnaya Square.
Dozens have been prosecuted and several sentenced to prison, including prominent opposition activist Sergei Udaltsov.
Kremlin opponents say the "Bolotnaya Case" is part of a campaign to stifle dissent.
They contend that protesters were provoked and that the state's claims of violence are strongly exaggerated.
Ishevsky pleaded guilty.
After his conviction and sentencing on October 10, nobody else is known to be in custody or facing trial for the protest.
