CHICAGO (AP) – Singer R. Kelly was arrested in Chicago Thursday after he was indicted on 13 federal counts including sex crimes, a U.S. Attorney’s office spokesman said. Joseph Fitzpatrick said the R&B singer was taken into custody about 7 p.m. local time and was being held by federal authorities. He was arrested after a 13-count federal indictment was handed down earlier Thursday in federal court for the Northern District of Illinois. “The counts include child porn, enticement of a minor and obstruction of justice,” Fitzpatrick said, adding that further details would be released Friday. The R&B singer already faces separate 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.
