Unidentified hackers attacked Tuesday the website of the Moscow-based court trying the case against the three performers of the Pussy Riot  punk group by posting on it a video of Bulgarian Roma gay singer Azis.

The hackers posted anti-government slogans and a provocative video clip by scandalous Bulgarian Roma pop-folk singer on the website of Moscow's Khamovnichesky District Court , according to Russian news agency Interfax.

Azis, who is of Roma origin, is widely known as the the platinum blond and openly gay king of Bulgaria's popfolk, a highly controversial genre of music combining Bulgarian with oriental motifs whose topics focus primarily on sex, money, and luxury properties.

It remains unclear why the hackers selected Bulgaria's popfolk king Azis to post a video of his on the website of the Russian court. Other than his provocative behavior, Azis has no connection to the Pussy Riot group, and his genre is very different from punk.

The original text on the homepage of Moscow's Khamovnichesky District Court was replaced with slogans calling for freedom for the Pussy Riot members and the titles of the website's sections were changed to sneering remarks about Russia's justice system.

Apart from that, a song of Pussy Riot called "Putin is Lighting the Fires of the Revolution" was also uploaded on the website.

A slogan reading "No Logic - Just Hardcore" was placed near the Russian coat of arms in the upper right hand corner of the webpage, as well as a mobile phone number signed "Ask for Zhenya".

According to experts, the attack was most probably staged by the Anonymous hacktivist group.

On August 17, The Khamovnichesky District Court sentenced the three members of the Pussy Riot punk band to two years in prison each.

Nadezhda Tolokonnikova, Maria Alyokhina, and Yekaterina Samutsevich were found guilty of "hooliganism motivated by religious hatred" after performing an anti-Putin "punk prayer" in the Cathedral of Christ the Savior in late February.
