A TV station in Chicago obtained video footage of an event that led to a criminal investigation into students at Glenbrook North High School in suburban Chicago.

Five students were allegedly injured in an annual initiation ritual that started off as a "powder puff" football game between seniors and juniors at the north suburban school.

The alleged hazing was so bad that authorities are considering possible criminal charges, WMAQ reported.

The video obtained by the TV station allegedly showed a homecoming tradition between senior and junior girls becoming rough and ugly when the seniors forced the junior girls to eat dirt, fish guts and pet food. Then the juniors were allegedly kicked around and had human excrement poured on top of them.

Five girls were sent to the hospital, one with a broken ankle.

Some of the girls who were present at the hazing said that they thought this year's event got out of hand but was "not that different from previous years."
