Brutal videos fuel Russian anti-gay campaign

Gay rights groups in Russia have said a new law restricting the spread of information about homosexuality has sparked a wave of violence against the gay and lesbian community.
The government denies persecuting sexual minorities and claims that the law is designed to protect children from what they say is harmful information.
But a number of videos posted online by a Russian vigilante group, appear to show the persecution of man in a bid to "cure him" of being a homosexual.
