Anastasia Rybachenko, an activist of the opposition Solidarity movement in Russia, has been put on a federal wanted list over her role in the May riots on Bolotnaya Square, the Investigative Committee said on Wednesday.

Rybachenko left Russia this past summer and currently lives in Estonia where she plans to complete her university studies after being expelled from college in Russia.

It turns out that Rybachenko was put on a wanted list September 11 but the committee only announced that now.

A rally at Moscow’s Bolotnaya Square on May 6 ended with clashes between protesters and police, who briefly detained some 650 people, according to rights activists’ figures.

Thirteen people were taken into custody in June on suspicion of instigating the riots or attacking police.
