Investigators are searching for a third day for a teenage girl they say stabbed five others during a melee that ensued after a high school football game in southeast Florida.

The incident occurred near the main entrance of Martin County High School on Friday night after a game against rival South Fork High School. Sheriff's spokeswoman Rhonda Irons said Sunday evening that investigators have not made an arrest.

In the incident, one person involved also was Tasered by a deputy. Authorities say another person was bitten by a police dog and one woman was arrested in a series of unrelated fights that involved around 30 people outside the school. None of the injuries were life threatening.

Detectives believe that a rivalry existed between those involved in the stabbings. South Fork beat Martin County 35-10.
