In Chicago, federal agents arrested R. Kelly Thursday night after a U.S. attorney brought a 13-count indictment against the musician, charging him with obstruction of justice, child pornography and other sex crimes. R. Kelly had been free on a $1 million bond as he faces other charges brought by Illinois prosecutors, including 10 counts of aggravated criminal sexual assault involving four women and girls, three of whom were under the age of 17 at the time of the alleged crimes.
