AMARILLO, Texas — 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.

Jail records did not list an attorney for Ayala.
