DALLAS -- A tour bus carrying hip-hop artist Snoop Dogg was pulled over and two people were arrested on marijuana possession charges Thursday a few hours before a concert in Dallas, a spokesman for the Texas Department of Public Safety said. DPS spokesman Charlie Morgan said members of a commercial vehicle inspection team pulled the bus over on Interstate 45 in Corsicana because the vehicle had an expired registration sticker. Troopers searched the bus for drugs after they said they smelled marijuana and found two ounces of the drug, he said. Ethan Calhoun, 27, and Kevin Barkey, 26, were arrested on drug charges after admitting the drugs belonged to them, Morgan told The Associated Press. Both men were taken to the Navarro County Jail and face fines of up to $2,000 and six months in jail if convicted, Morgan said. Bond was set at $1,500 each.
