Several members of the Theta Chi fraternity, whose house is on the San Diego State campus, were among those arrested in the drug investigation.

Students walk between classes on the campus at San Diego State, where dozens of students were arrested on drug charges after an undercover investigation that centered on fraternity row’s freewheeling party atmosphere. “This operation shows how accessible and pervasive illegal drugs continue to be on our college campuses and how common it is for students to be selling to other students,” said San Diego County Dist. Atty. Bonnie Dumanis.  (Don Bartletti / Los Angeles Times)
