Six Streamwood High School students were arrested Tuesday in connection with a fight that broke out on campus, police said.
No weapons were used in the fight, and no significant injuries to students or staff were reported as a result of the 11:15 a.m. altercation, Streamwood police said.
As of Tuesday night, police had not released the names, ages or sexes of the students, or whether any have been charged with a crime.
Students not involved in the fight were held temporarily in their classrooms and kept from moving from class to class, said Patrick Mogge, spokesman for Elgin Area School District U-46.
The restriction was lifted Tuesday afternoon, and the school was not placed under lockdown, he added.
Mogge would not say what started the fight.
However, according to one student, the melee began with two students who, at first, were considering going outside to fight, then decided to do it right inside the school.
The student said the fray stemmed from a dispute that had been simmering since last summer between students who live in Hanover Park and those who live in Streamwood.
Classes were dismissed at their normal time Tuesday, but parents were allowed to pick up their children earlier if they wanted.
Schaumburg, Hoffman Estates, Bartlett, Hanover Park police and the Cook County Sheriff's Office joined Streamwood police in responding to the school for precautionary measures, authorities said.
The district plans to have extra supervision at the school Wednesday morning.
