CHAPEL HILL, N.C. (AP) -- University of North Carolina chancellor Carol Folt says the school has fired or begun disciplinary procedures against nine employees after an investigation of an academic fraud scandal dating back nearly two decades.

Folt took questions from reporters Wednesday after the release of the report by former U.S. Justice Department official Kenneth Wainstein. Folt says four people are being terminated. She wouldn't say who they were.

Wainstein's probe found more than 3,100 students - nearly half of them athletes - enrolled in classes they didn't have to show up for and received artificially inflated grades for research papers. The report called it a ''shadow curriculum'' that ran from 1993 to 2011 in the former African and Afro-American Studies department.
