WWW- Jeffrey Jones, who had the infamous role as the high school principal in “Ferris Bueller’s Day Off,” will soon find himself back in court on allegations that he took sexual advantage of a 14-year-old boy.

The boy is now an adult and he’s suing Jones personally. “CJ” has obtained the graphic lawsuit, which accuses Jones of doing unthinkable acts, such as touching the boy’s genitals and demanding that he pose nude and touch himself for the camera.

The suit also claims that Jones gave the boy various costumes to wear, including cowboy, sailor and Indian outfits.

Jones faced criminal charges last year for taking explicit photos of the boy, a charge to which he pleaded “no contest.” At the time, Jones said, “Such an event has never happened before and it will never happen again.”

Jones’ was sentenced to five years of probation and the judge ordered him to register as a sex offender. At the time, his lawyers, Leonard Levine and Jeff Brody, told “CJ” that it was the best Jones could have gotten. But the suit now claims it was a lot more than just photographs — that there was physical contact and the alleged abuse has caused severe emotional problems, including suicidal tendencies.

But prosecutors never charged Jones with any physical abuse and believed the case had been fully resolved.

Jones apparently did too. Now he’s been hit with an ugly lawsuit demanding unspecified damages. The suit also claims the accuser, who is now 19 years old, has a difficult time having relationships with women because of Jones’s alleged misconduct.

Jones’ attorney tells us the new claims are blatantly false and that the suit is totally about money.
