Greg Anderson, who was Barry Bonds' personal trainer, was being held in contempt of court for refusing to testify against his childhood friend.

Barry Bonds’ personal trainer Greg Anderson has been set free.

A federal judge ordered Anderson released from prison on Thursday.

The order came just hours after Bonds was indicted by a federal grand jury on charges of perjury and obstruction of justice, stemming from the ongoing investigation into the use of performance-enhancing drugs in baseball.

Anderson was released from prison and refused comment as he walked out.

Anderson’s attorney, Mark Geragos, said the trainer didn’t cooperate with the grand jury that indicted Bonds.

“This indictment came out of left field,” Geragos said. “Frankly I’m aghast. It looks like the government misled me and Greg as well, saying this case couldn’t go forward without him.”

Anderson was to remain in jail for six months, or until the grand jury investigating Bonds on perjury charges expired.

The 41-year-old Anderson previously spent three months in jail and three months on home detention for pleading guilty to steroid distribution and money laundering in the investigation of the Bay Area Laboratory Company.

A childhood friend of Bonds, Anderson was ordered back to jail last August after being held in contempt of court for refusing to testify against the all-time home run king and Detroit Tigers outfielder Gary Sheffield.

Bonds’ indictment stems from his testimony to a grand jury that he did not knowingly use steroids and that Anderson gave him what he believed to be flaxseed oil and arthritic balm.
