The Anniston Star reports that the new arrests bring the total to 13 in the investigation involving a Jacksonville State fraternity.
Some suspects face charges of first-degree assault, which is a felony, and misdemeanor hazing. Others face only hazing charges.
Calhoun County District Attorney Brian McVeigh announced in October that a grand jury had issued indictments stemming from a Nov. 26, 2011, incident involving a JSU fraternity and that more indictments were expected.
The fraternity, JSU's chapter of Alpha Phi Alpha, has since been dismissed from campus. A university official has said that the incident was one of the worst hazing cases the school has seen.
