Charging documents say the student told police that current or former Zeta Phi Beta sorority members assaulted her off campus at least three times, including pushing her into a wall and striking her with an oak paddle.
Police say the student's arms and chest were severely bruised. Most of the women charged are scheduled to appear in court Thursday morning. The university says the sorority was suspended in November after officials learned it didn't follow pledging guidelines.
Of the seven members who were criminally charged with engaging in illegal acts during pledging, three are students and at least two are university alumnae.
