Prosecutors say a man facing terrorism charges for allegedly trying to bomb a downtown Chicago bar is now accused of seeking to have an undercover FBI agent killed while the suspect was behind bars.

The U.S. attorney's office says 19-year-old Adel Daoud (dah-OOD') faces multiple charges, including solicitation of murder or attempted murder of a federal agent and murder-for-hire.

The Hillside teen has been jailed since his arrest last year for allegedly trying to ignite what he thought was a car bomb outside a bar. He's pleaded not guilty to the charges in that case.

Reached by phone Thursday, Daoud's attorney, Thomas Durkin, didn't have an immediate comment.
