BEREZNIKI, Russia (January 16, 2013)--A Russian court has turned down the attempt by an imprisoned member of the Pussy Riot feminist punk band to defer her prison sentence until her preschool son becomes a teenager.

Maria Alekhina on Wednesday asked the court to let her serve the rest of her two-year sentence after her 5-year-old son turns 14, arguing that separation from her child now will do irreparable psychological damage.

She was convicted last year along with two other band members of hooliganism motivated by religious hatred for an anti-President Vladimir Putin stunt in Russia's main cathedral.

One of the women’s sentence was suspended on appeal.

Judge Galina Yefremova rejected the petition, saying the court that sentenced Alekhina had already taken the child's existence into account.
