A prosecutor says he has dismissed a felony fraud charge against a former North Carolina professor linked to a scandal involving academics and athletics.

In a statement Thursday, Orange County district attorney Jim Woodall said he dropped the charge after Julius Nyang’oro cooperated with the criminal investigation and an independent probe into fraud in the department where Nyang’oro served as chairman.

A grand jury indicted Nyang’oro in December for obtaining property by false pretenses. He was charged with receiving $12,000 to teach a summer 2011 lecture class that did not meet. The class, filled with football players, was treated as an independent study requiring a research paper.

Former U.S. Justice Department official Kenneth Wainstein is leading the independent probe into the formerly named African and Afro-American Studies department.
