AMARILLO, Texas (AP) - An Oklahoma City man has been arrested after a Texas Panhandle traffic stop yielded $1 million in methamphetamine.    

Carson County jail records show 20-year-old Ernesto Ayala was being held Monday on a charge of felony possession of a controlled substance.    

The Texas Department of Public Safety says one of its troopers stopped Ayala on Saturday for a traffic violation near Conway, about 20 miles east of Amarillo.    

The trooper discovered several plastic-wrapped packages of methamphetamine weighing more than 12 pounds concealed inside the panels of Ayala's car.

DPS says the drugs were being transported from San Diego to Oklahoma City.
