The NCAA has reopened its investigation into the academic scandal that has rocked North Carolina over the past three years.

"The University of North Carolina, Chapel Hill, was cited by the Division I Committee on Infractions in 2012 for violations in its athletics program, including academic misconduct," the NCAA said in a statement. "As with any case, the NCAA enforcement staff makes clear it will revisit the matter if additional information becomes available. After determining that additional people with information and others who were previously uncooperative might be willing to speak with the enforcement staff, the NCAA has reopened its investigation.

"The enforcement staff is exploring this new information to ensure an exhaustive investigation is conducted based on all available information. The NCAA will not comment further to protect the integrity of the investigation."

In 2012, the NCAA sanctioned the North Carolina football program with a postseason ban and scholarship losses after finding impermissible benefits and academic fraud under then-coach Butch Davis.

Since 2011, the university has conducted several reviews related to the academics scandal and provided the NCAA with updates. North Carolina announced in 2012 that it had found problems with 54 AFAM classes taught from summer 2007 to summer 2011, including grade changes, forged faculty signatures on grade rolls and limited or no class time.

North Carolina forwarded the results of that investigation to the NCAA, which ruled the university did not break any rules related to the AFAM scandal.

In February, the university hired former federal prosecutor Kenneth Wainstein to conduct an independent investigation and instructed him to share relevant information directly with the NCAA.
