Brock Lesnar, the World Wrestling Entertainment champion, was once arrested for illegally possessing steroids, though the felony charge against the 26-year-old athlete was dismissed four months after his January 2001 arrest. Lesnar, pictured in the below mug shot, was popped by Louisville Division of Police detectives after receiving and opening a parcel that cops said contained a "large amount of steroids." Lesnar, a 295-pound former college wrestling champ, was in Kentucky training at a WWE facility. Hit with a trafficking in controlled substances charge, Lesnar was exonerated when tests showed that the seized pills were not, in fact, steroids. While a Louisville detective told TSG that the material was some kind of growth hormone, Lesnar's defense attorney, Scott Cox, characterized the confiscated pills as a "vitamin type of thing." According to Cox, officers seemed "very apologetic" when lab results cleared Lesnar. It is unclear how investigators concluded that the parcel sent to Lesnar may have contained illicit substances.
