Witnesses told ABC11 it involved a broken bottle and video from the scene showed a student being taken away in an ambulance.
It happened at Valentine Commons at 3009 ME Valentine Drive.
The witnesses - who live next door - told ABC11 one roommate attacked two other roommates. A motive wasn't clear. All of the students involved are undergraduates.
