Moscow law enforcement authorities shut down a Tuesday night “Vulva 3.0” documentary screening in support of Yulia Tsvetkova, an LGBT activist who is being prosecuted for her drawings of female genitals.

She has been fined twice under a controversial law banning propaganda of “non-traditional” sexual relationships to minors for her drawings and for running LGBT-themed groups on social media.

The National Guard later told the independent Dozhd news channel that its forces were not deployed to the screening’s venue.

Police in Russia’s Far East opened a third “gay propaganda” case against Tsvetkova this summer over drawings on social media protesting Russia’s constitutional amendments outlawing gay marriage. Russia’s Memorial human rights group has declared Tsvetkova a political prisoner.
