SAN DIEGO - A man arrested in connection with a drug sweep at San Diego State University and nearby fraternities pleaded guilty Monday to possession for sale of cocaine and was immediately sentenced to three years in prison.

Superior Court Judge David Danielsen ordered Omar Arce Castaneda, who never attended SDSU, to register as a narcotics offender.

Prosecutors alleged that the 37-year-old defendant was a cocaine distributor who acted as a middleman between students and Mexican drug cartels, and that he was a documented gang member from Pomona.
