Austin Lee Russell, known to viewers of the A&E network's Pawn Stars as Chumlee, was arrested Thursday after police discovered methamphetamine, marijuana and at least one firearm at his home in Las Vegas.

Officers came to the residence while pursuing a sex-crime investigation, though no charges were filed in relation to that. That investigation is continuing separately.

Russell was taken into custody then released on bond, according to the Clark County district attorney's office. He will appear in court on Friday to respond to 19 drug-related charges and one weapons charge.

Russell's co-star on Pawn Stars, Rick Harrison, told Fox411 in an email that "We don't have details yet, but we are here to help Chumlee any way we can.” Russell himself has not yet commented publicly.
