NORTHBROOK, Ill. (May 9[2003]) - A videotaped hazing in which high school girls were pummeled and showered with feces, paint and garbage has humiliated and shocked students and administrators at a suburban Chicago high school that once enjoyed a prestigious reputation.

``It's devastating to our school and to our community,'' said Glenbrook North High Principal Michael Riggle.

Authorities are trying to determine whether parents supplied beer and some of the filth.

``It's annoying and embarrassing, because there are a lot of good people at GBN,'' junior Judd Hack, 17, said Thursday. ``But it shouldn't be covered up either, because this is brutality to another human being by drunken buffoons.''

The melee, videotaped by students and involving as many as 100 teenagers, occurred Sunday during a girls' touch football game in a park in this well-to-do suburb. Seniors had invited juniors for what was described as an initiation into their senior year.

Five girls were hospitalized, including one who broke an ankle and another who suffered a cut that required 10 stitches in her head.

Cook County Forest Preserve District police said Thursday that they probably will file criminal charges. Spokesman Steve Mayberry said he did not know the charges or how many people might be charged.

Two parents might have supplied kegs of beer, said school board member Tom Shaer.
