Six students were arrested following a fight at Streamwood High School that put the northwest suburban school in "hold in place" mode Tuesday afternoon.
In a message posted to the school's website, District U-46 said police were called after students were involved in a fight.
"We had an altercation with multiple students involved and the police are currently at the school," school officials said.
Details weren't given on the nature of the altercation, but the district said the situation was calm after police arrived and students remained in their classrooms.
Six students were arrested and no significant injuries were reported, according to a release from Streamwood police. No weapons were used in the fight.
In a second message posted to the school's website, the district said police will continue to stay in the building and school will dismiss as normal.
Parents can pick up their students early at the east gym entrance at door 12 if they present identification.
