Australian actor Robert Hughes has been convicted of an indecency charge after exposing himself to a young girl on the set of his Tv show Hey Dad!.

The verdict came in on Tuesday (08Apr14), a day after the former Hey Dad! star was convicted on nine sex abuse charges, including two counts of sexual assault and seven counts of indecent assault relating to victims aged between seven and 15 years old.

A jury at Sydney's Downing Centre District Court found the actor guilty of a charge of committing an act of indecency dating back to an incident on the Tv show's set in 1990, but they were unable to reach a verdict on a second indecency charge before they were dismissed.

Hughes, 65, is due to be sentenced in May (14). His lawyer expects the actor to launch an appeal.
