Controversial baseball slugger Barry Bonds was indicted by a federal grand jury on Thursday for perjury and obstruction of justice charges for lying about whether he ever took performance enhancing drugs.

The indictment, unsealed Thursday by federal prosecutors in San Francisco, is the culmination of a four-year federal probe into whether he lied under oath to a grand jury investigating steroid use by elite athletes.

While Bonds was chasing Aaron amid the adulation of San Franciscans and the scorn of baseball fans almost everywhere else, due to his notoriously prickly personality and nagging steroid allegations, a grand jury quietly worked behind closed doors to put the finishing touches on the long-rumored indictment.

Bonds, baseball’s all-time and single season home run leader, is a free agent. He has stated that he wants to play at least one more year. If he plays, he will likely sign with an American League team so he can play designated hitter.
