LOS ANGELES (AP) – Actor Jeffrey Jones, best known as the suspicious high school principal in “Ferris Bueller’s Day Off,” was arrested Thursday for allegedly having sex with a 17-year-old boy and possessing child pornography, authorities said.

Jones, 56, surrendered and was freed on $20,000 bail, said Officer Jason Lee, a police spokesman. Arraignment was scheduled for Nov. 21.

Jones was charged with one count each of using a minor for sex acts and possession of child pornography, said District Attorney’s spokeswoman Sandi Gibbons. She said the alleged victim was a 17-year-old boy.

Police began investigating Jones last November after a minor came forward and “alleged criminal acts of a sexual nature,” Lee said.

Investigators subsequently searched Jones’ home and seized “numerous items of evidence,” Lee said. He did not elaborate.

Jones could not be reached for comment. There is no listing for him in the Los Angeles area and the Screen Actors Guild did not immediately respond to a request for his agent’s number.

A widely recognized character actor, Jones played the music-loving Emperor Joseph II in “Amadeus,” the mentalist Criswell in “Ed Wood” and the father in “Beetlejuice.”
