Barry Bonds tested positive for steroids in November 2000, less than a year before he broke baseball’s season home run record, U.S. prosecutors charged Thursday.

The U.S. attorney’s office in San Francisco charged in an indictment released in November 2007 that Bonds had tested positive for “anabolic steroids and other performance-enhancing substances.”
