R. Kelly arrested in Chicago on federal sex crime charges

CHICAGO -- A U.S. Attorney's office spokesman says singer R. Kelly has been arrested on federal sex-crime charges in Chicago.

The 52-year-old R&B singer was arrested in Chicago by New York Police and Homeland Security investigators, WGN reported.

U.S. attorney spokesman Joseph Fitzpatrick says the 13-count indictment includes charges of child pornography, enticement of a minor and obstruction of justice. Other details were not immediately released.

The R&B singer already faces state sex-related charges in Illinois involving four women, three of whom were minors when the alleged abuse occurred. He pleaded not guilty to those charges and was released on bail.
