A Kentucky grand jury has subpoenaed the publisher of the book by an escort that alleges former Louisville basketball staffer Andre McGee hired her and other dancers to strip and have sex with recruits and players.

A text statement to The Associated Press from Kate Snedeker, a spokeswoman for IBJ Book Publishing, said Friday, ''we recently received the document with regard to which we are considering an appropriate response.'' The publisher is an affiliate of the Indianapolis Business Journal.

Larry Wilder, the Jeffersonville, Indiana-based attorney for escort Katina Powell, declined comment Friday on the grand jury proceedings, citing secrecy restrictions. But he said via text that his client ''has not received any subpoena from the Commonwealth or any other government agency.''

Neither Scott C. Cox, McGee's Louisville-based attorney, Louisville basketball spokesman Kenny Klein, nor the Commonwealth's Attorney's Office had comment when contacted by the AP.

Powell's book, ''Breaking Cardinal Rules: Basketball and the Escort Queen,'' alleges that Andre McGee paid her $10,000 for 22 shows from 2010-14, with many taking place at the players' Billy Minardi Hall dormitory. Louisville coach Rick Pitino has denied knowledge of the activities described in Powell's book.

The allegations have led to four investigations. Louisville's athletic department and the NCAA launched theirs in August after the school was notified about them and contacted the governing body. Louisville campus police are working with Louisville Metro Police and the Commonwealth's Attorney's Office for possible criminal charges.

The University of Louisville Foundation has hired a law firm to review the allegations.

On Tuesday, Wilder said in a radio interview that his client wasn't likely to cooperate with authorities or the NCAA without some protection from prosecution. ''She can't do that unless we have assurances that there will not be a pursuit of criminal charges against her, based upon the information,'' he said.
