CBS News Chief Investigative Correspondent Armen Keteyian, who spent many years with CBS Sports, is working on a series on the pervasiveness of gangs in college athletics. “Gangs in Sports” will air tonight on the CBS Evening News and tomorrow morning on “The Early Show.”

The series is in conjunction with Sports Illustrated, where Keteyain was a reporter early in his career in the 1980s.

Keteyian and SI contributing writer Jeff Benedict traveled to Compton, CA to get a look at the intersection of gangs in sports at three local high schools. Keteyian and Benedict rode along with a supervisor in the LA Sheriff’s Department’s Gang Unit. He’ll also profile several high school stars fighting to avoid the violence in the streets as they try to break into top college football programs.
