Five months of regular sexual abuse in 2003 lead to the arrest of a 61-year-old Provo man Wednesday.

The man allegedly told police he made his mentally retarded stepdaughter perform sex acts on him four or five times a week at his Provo home between January and May of 2003, according to documents filed in 4th District Court. The man also allegedly admitted to fondling the woman a number of times during the same period.

The stepdaughter, who is 36, has the mental capacity of a 7-year-old. The man was arrested for investigation of forcible sexual abuse and is being held on a $10,000 cash bail.
