NEW YORK (AP) - Sharon Stone will soon be fighting crime in a guest role on "Law & Order: Special Victims Unit."

The Oscar-nominated actress will appear on the NBC cop drama in a four-episode story arc later this season, says Pam Golum, a spokeswoman for producer Dick Wolf.

Stone, best known for her films "Basic Instinct" and "Casino," will play a cop turned prosecutor.

In the past, she has guest-starred on the series "Huff" and "The Practice," for which she won an Emmy.

Her casting was first reported Tuesday by Entertainment Weekly's Web site.
