LOS ANGELES: Police arrested former vice president and current environmental activist Al Gore's son, also named Albert Gore, after finding marijuana and narcotics in his low-emissions car, authorities said on Wednesday.

Orange County Sheriff's deputies spotted Gore's blue Toyota Prius going more than 100 miles per hour (160 kph) on the I-5, the main north-south highway on the west coast, on Wednesday.When they pulled him over, they smelled marijuana, searched the car and found more of the drug, as well as vicodin, valium, xantax, and adderal, which is used to treat attention deficit disorder.

“He did not have prescriptions for any of these medications,” sheriff's department spokesman Jim Amormino told newsmen.

Gore was arrested and is being held on 20,000 bail. “He is still in custody,” Amormino said.

Gore, 24, lives in Los Angeles and told authorities he was headed south to San Diego, Amormino said. The arrest comes just days before Al Gore senior is due to join a series of concerts to raise awareness of global warming, “Live Earth.”—AFP
