A Russian opposition activist has been placed under arrest for 15 days after an incident in which his wife said he did nothing wrong.
A court in the southern city of Krasnodar found Leonid Martynyuk guilty of minor hooliganism on August 27 after he was pushed and cursed by a stranger at a railway station.
Martynyuk's wife, Yekaterina Zavgorodnyaya, said on Facebook that her husband was detained after reporting the incident to police.
Journalist and blogger Martynyuk is a member of the opposition Republican Party of People's Freedom (PARNAS).
He and Boris Nemtsov, another prominent critic of President Vladimir Putin, wrote a report about alleged corruption during preparations for 2014 February Sochi Winter Olympics.
Martynyuk has shot a series of documentaries called "The Lies of Putin's Regime." The last one is about the downing of a passenger jet that crashed in Ukraine, killing 298 people.
