Not guilty plea

R Kelly pleads not guilty to sexual assault

The new counts, unveiled last week in an indictment by a Cook County grand jury, involve alleged abuse of a victim between the ages of 13-16, according to documents posted on the Chicago Sun-Times' website.

The allegations centre on someone identified only as J.P., with no other details provided. The alleged crimes allegedly took place between May 2009 and January 2010.

Kelly, 52, could face up to 30 years in prison if convicted on the new charges.
