R. Kelly has been arrested in Chicago on federal sex crime charges.

According to law enforcement officials, the 52-year-old singer was arrested by NYPD detectives and Homeland Security Investigation agents in a 13-count indictment on Thursday (July 11), reports TMZ.

Joseph Fitzpatrick, spokesperson for The U.S. Attorney’s Office of the Northern District, says the indictment includes charges of child porn and obstruction of justice.

Back in February, Kelly was charged with 10 counts of aggravated criminal sexual abuse involving four women, three of whom were minors at the time. He pleaded not guilty and was released from Chicago’s Cook County Jail after posting bail.

In May, an Illinois grand jury indicted the R&B superstar on 11 new charges in his sexual assault and sexual abuse case, including four new felonies that carry maximum penalties of 30 years in prison.

Further details on the case are expected to be announced Friday.
