27 year old Benjamin Oakes of Waterville made a video appearance in an Augusta courtroom Monday afternoon.
Oakes was arrested Friday night.
Police say he assaulted a woman who was walking her dog Thursday near the entrance of Colby College.
In the last two months two other attacks on women on campus have been reported.
Police say the three cases are unrelated.
Oakes has four prior assault convictions on his record dating back to 1998.
Oakes is being held at the Kennebec County Jail without bail.
