Chumlee, whose real name is Austin Lee Russell, was arrested Wednesday on 19 charges of drug possession and a single charge of possessing a gun by a prohibited person. His bail was set at $62,000.
Police were serving a search warrant at his house as part of a sexual assault investigation and found methamphetamine, marijuana and firearms, according to police.
Metro said the 33-year-old reality TV star has not been charged with sexual assault, but the investigation is ongoing.
A records search for Austin Russell in Clark County courts turns up only minor traffic offenses. He is scheduled to appear in Las Vegas Justice Court on May 23 to face the gun and drug charges.
Chumlee quickly became a reality TV celebrity in 2009 when the show profling the daily operations of Gold & Silver Pawn Shop, 713 Las Vegas Blvd. South, premiered on the History Channel.
Laura Herlovich, personal publicist for the store’s owners and Chumlee, declined to comment on the the arrest.
