The estranged wife of the publisher of the Pittsburgh Tribune-Review was arrested Thursday and charged with defiant trespass after refusing to leave her husband's Shadyside residence.

Pittsburgh police said they were called to the home of Richard Mellon Scaife, at 5201 Westminster Place, at about 7 p.m. Thursday. Mr. Scaife called police because his wife, Ritchie Scaife, was pounding on doors and peeking in windows.

When police arrived, Mrs. Scaife, who was in the back yard, was told to leave. She did, but only for about 15 minutes, police said. When she returned, she refused officers' orders to leave and was arrested. She was charged with defiant trespass and released on her own recognizance.

A hearing is scheduled for Thursday.
