LOUISVILLE, Ky. (WDRB) -- The Commonwealth’s Attorney’s Office has issued at least one grand jury subpoena in the University of Louisville basketball program sex scandal.

IBJ Book Publishing, which published "Breaking Cardinal Rules: Basketball and the Escort Queen," confirmed to WDRB on Friday that they have received a subpoena to appear before the grand jury on November 5.

ESPN reported Friday that a source told them the Commonwealth's Attorney's Office had begun issuing subpoenas.

Assistant Commonwealth's Attorney Jeff Cooke said he could not talk about grand jury proceedings.

Katina Powell, 42, has claimed that she hosted 22 stripping and sex parties from 2010 to 2014 inside Billy Minardi Hall, the on-campus dorm for athletes.

Powell has said that former Louisville graduate assistant Andre McGee arranged the parties and paid her $10,000 for supplying dancers.

Larry Wilder, an attorney for Powell, said that "Kentucky grand jury proceedings are secret. And Kentucky law prohibits anyone who has received a grand jury subpoena from commenting. However, as of this moment Ms Powell has not received any subpoena from the Commonwealth or any other government agency."

It is unlikely Powell would be subpoenaed, as she could not be compelled to testify against herself.  

Attorney Scott C. Cox, who represents McGee, said: "I don't have any comment on the investigation. We will just wait until it's finished."

Dick Cady, Powell's coauthor, could not be immediately reached for comment.

A grand jury is made up of 12 citizens, who, often at the request of prosecutors, can subpoena records and witnesses. It is a secret process, with details typically only revealed when they reach a decision whether to indict someone or not. Nine of the 12 jurors have to agree.

Assistant Commonwealth’s Attorney Chris Foster, who is in charge of a unit that prosecutes crimes against children, is handling the case.

Commonwealth's Attorney Tom Wine has said the allegations from the book cause "grave concern to me and this community."

"If my office receives credible evidence of sexual abuse or other criminal activity involving minor children, we will vigorously prosecute those responsible for those crimes."
