CORAL GABLES, Fla. (AP) — The NCAA has found what it calls "a very severe issue of improper conduct" committed by former members of its own enforcement program during the Miami investigation, and will not deliver the long-awaited notice of allegations against the Hurricanes until an external review is completed.

NCAA President Mark Emmert announced the findings Wednesday. The sports governing body said former enforcement staff members worked with the criminal defense attorney for former Miami booster and convicted Ponzi scheme architect Nevin Shapiro "to improperly obtain information ... through a bankruptcy proceeding that did not involve the NCAA."

"I am deeply disappointed and frustrated and even angry about these circumstances," said Emmert, who also described it as "a shocking affair."
