R. Kelly pleads not guilty to new charges of child pornography and sexually abusing a teenager

R. Kelly has pleaded not guilty to an updated federal indictment that includes child pornography charges and abuse allegations from a new accuser.

Kelly, 53, wore prison garb before a judge while his attorney entered the plea on his behalf at an arraignment hearing in Chicago on Thursday.

Authorities recently seized more than 100 electronic devices, including cell phones and hard drives, in the case against Kelly and prosecutor Angel Krull said the government plans to file more charges in the upcoming weeks.

A new accuser has also come forward, but the details of their claims have not been made public.

Potential of new charges was one of the reasons U.S. District Judge Harry Leinenweber pushed the R&B singer’s April 27 trial to October 13.
