Victoria, Australia's second most populous state, banned the popular video-sharing site from its 1,600 government schools after a gang of male school students videotaped their assault on a 17-year-old girl on the outskirts of Melbourne.

The assault, which is being investigated by police, was uploaded on YouTube late last year.

Education Services Minister Jacinta Allan said the schools and their Internet service providers already filtered the Web sites that were available to students, and YouTube had been added to a list of blocked sites.

The state government "has never tolerated bullying in schools and this zero tolerance approach extends to the online world," Allan said.

"All students have the right to learn in a safe and supportive learning environment ¡ª this includes making students' experience of the virtual world of learning as safe and productive as possible," she said.

YouTube is a free video-sharing site that lets users upload, view, and share video clips.
