Kids 'shown porn instead of Jonas Bros'

A class of schoolchildren in New York were accidentally shown part of a pornographic film instead of a Jonas Brothers movie, it has emerged.

Students as young as five were exposed to 45 seconds of sexually explicit footage when the teacher powered up the DVD player and walked off to find the copy of Camp Rock, the New York Post reports.

Rona Easton, whose six-year-old son Cass was in the class, said: "My son told his friend he saw a naked lady at school. I thought he was just being silly. It's appalling."

Principal Robert Marchi sent a letter to parents that read: "A very explicit pornographic video came on the screen. This was extremely upsetting to the students and staff members in attendance.

"I am deeply sorry that this episode took place. I know that we will make every effort to find out who was responsible for this despicable act."
