LA PORTE, Ind.  Kevin Kunst, the athletic director at La Lumiere School, said on Wednesday that the N.C.A.A. is engaged in a wide investigation of the Baylor University’s men’s basketball program that includes its recruitment of Hanner Perea, a forward from Colombia who is widely considered one of the best 25 high school juniors in the country.

FoxSports.com first reported the investigation on Wednesday, causing a stir among administrators at La Lumiere, a private school best known as the alma mater of Chief Justice John G. Roberts Jr.

The N.C.A.A. investigator Kristen Matha came here last month to question La Lumiere Coach Alan Huss. While Huss declined to reveal details of the conversation, Kunst said that the N.C.A.A. visit involved a larger investigation into Baylor.

“La Lumiere is not at question at all in any shape or form,” Kunst said. “This really has to do with what appears to be a significant, ongoing and much broader investigation of Baylor than this little thing. I think we’re the piece of a larger puzzle.”
