MOSCOW, March 13 (RIA Novosti) - Russia's Interior Ministry said on Friday several dozen patients at a drug rehabilitation center in the Perm Region, in the Urals, have been brutalized by staff.

Police said they raided the Delfin drug rehabilitation center in the town of Krasnokamsk on Thursday and discovered CDs and photos showing acts of violence being performed on the patients.

Handcuffs, clubs and an instrument to administer electric shocks were also found at the center, which had a total of 96 patients.
