Jocelyn Walker, 18; Antoine Cantrell, 19; and Ryan Hattaway, 20, were arraigned Thursday on three counts of armed robbery.
Hattaway and Cantrell attend Kalamazoo Valley Community College. Walker is a student at Western Michigan.
Western Michigan students were urged to use caution following a pair of Dec. 6 armed robberies that took place within minutes on campus. No one was injured. There was also a robbery of an off-campus convenience store that night by two men.
Hattaway, Cantrell and Walker were arrested Monday following a purse snatching in Oshtemo Township.
