Attempts since 2006 to hold the event have consistently been met with official bullying, arrests, and clashes with police and right-wing counterprotesters.
Among those detained by the police were both those marching for gay pride and right-wing demonstrators who attacked them.
Choi was later released. But here he gives a status report from the police van following his arrest:
RFE/RL's Russian Service also reported that "Novaya gazeta" correspondent Yelena Kostyuchenko, who took part in the rally, was hospitalized with a concussion.
Permission was denied again for the march this year, despite the fact that the European Court of Human Rights ruled in October 2010 that Moscow had violated the European Convention on Human Rights by forbidding the rallies in 2006, 2007, and 2008.
