Substances suspected to be anabolic steroids were seized from the home of Barry Bonds' personal trainer during a Sept. 5 raid by federal investigators, two sources close to the search told the San Francisco Chronicle in Monday's editions.
A search of Greg Anderson's house also discovered information that detailed athletes' names, the names of drugs they may be using and apparent drug intake schedules, according to the Chronicle report. There was no information in the report linking Bonds himself to the drugs or the recorded information.
The raid on Anderson's home was part of an ongoing federal investigation into an international sports doping ring. Anderson has given a statement to investigators, according to his lawyer, William Rapoport, who seemed unconcerned by the report.
"I've been given nothing to indicate that anything taken from [Anderson's] house qualified as a steroid," Rapoport told the Chronicle.
Last Tuesday, Bonds said he could not comment on the investigation. His attorney, Michael Rains, told the Chronicle that he wasn't worried by the latest details regarding the search of Anderson's home.
"I'm aware that Greg trained a number of other athletes other than Barry, a lot of nonathletes and bodybuilder types, as well," Rains told the paper. "Whatever they found, if they did find steroids, doesn't worry me so far as any relation to my client."
The search of Anderson's home came two days after federal investigators had raided the Bay Area Laboratory Co-operative (BALCO), a Burlingame, Calif., company that provided nutritional supplements and blood-testing services to top-level athletes.
BALCO, and its owner, Victor Conte, have been accused of manufacturing THG, a previously undetectable designer steroid now appearing in the track and field and professional football arenas.
A number of professional athletes, including Bonds, have been subpoenaed to testify in grand jury hearings related to the BALCO investigation. Bonds is scheduled to testify on Dec. 4.
