Blues Traveler frontman JOHN POPPER was arrested in Washington state on Tuesday (06MAR07) after police who pulled him over for speeding discovered a cache of weapons and marijuana in his car. According to the Washington State Patrol, the 39-year-old's black Mercedes Sports Utility Vehicle (SUV) was clocked at 111 miles per hour (179 kilometres per hour). Popper, who lives in Washington, owns the car, but BRIAN GOURGEOIS, of Austin, Texas, was driving the vehicle at the time. According to Officer JEFF SEVIGNEY, authorities searched the car with a police dog and found four rifles, nine handguns and a switchblade knife in a secret compartment. Police also found a Taser, night vision goggles and a small amount of marijuana. The vehicle was also equipped with flashing emergency headlights, a siren and a public address system. The authorities immediately seized the SUV. According to the police report, "Popper indicated to troopers that he had installed these items in his vehicle because (in the event of a natural disaster) he didn't want to be left behind." Popper also told officers he collected weapons. Both men were booked at the Adams County Jail and released on their own recognizance. Authorities plan to charge both men with possession of a controlled substance and possession of drug paraphernalia. Gourgeois also faces a reckless driving charge.
