RnB sensation,R. Kelly has been arrested on federal child pornography and obstruction of justice charges.

The U.S. Attorney’s Office in Chicago said the pop star was arrested Thursday on a 13-count indictment.

“He was arrested on charges contained in a 13-count indictment returned today in the Northern District of Illinois,” the Attorney’s Office said in a statement late Thursday adding that “The indictment includes charges of child pornography and obstruction of justice.”

R Kelly is also facing 10 counts of felony criminal sexual abuse involving four alleged victims, after being arrested by the Cook County Sheriff’s Department in March. He has pleaded not guilty to those charges, some of which date back to 1998.

The 52-year-old has always denied allegations of sexual misconduct. The singer was acquitted of  child pornography charges in 2008.
