Police in Russia are searching for other members of punk band Pussy Riot in connection to the band's controversial protest song Performance in a church earlier this year.

Three members of the group, Nadezhda Tolokonnikova, 23, Maria Alekhina, 24, and Yekaterina Samutsevich, 29, were found guilty of hooliganism charges on Friday after taking aim at President Vladimir Putin in song during a Moscow church service in February.

They were sentenced to two years behind bars for the crime, and now it's emerged detectives are looking to track down other Pussy Riot bandmates they suspect of taking part in the incident.

Cops confirmed the news on Monday, but admitted they had yet to identify the group members.

It is not known how many suspects they are seeking or whether they will face similar charges when found.

Reports suggest five members of the masked feminist band stormed Moscow's Christ the Saviour Cathedral, but only three were caught and put on trial.

The band released a new song, titled Putin is Lighting the Fires of Revolution, on Friday in response to the trio's controversial conviction, which prompted stars including Madonna and The Black Keys to call for its release.
