EL PASO, Texas >> Agents at a border crossing in West Texas have seized nearly $1.3 million worth of cocaine hidden in an SUV’s spare tire.

U.S. Customs and Border Protection officials in El Paso on Thursday announced a woman from Mexico has been detained on drug smuggling charges.

The case involves nearly 40 pounds of cocaine seized Wednesday afternoon during a vehicle search at the Bridge of the Americas. Investigators say a drug-sniffing dog alerted officers to the undercarriage of the SUV.

Officials say the spare tire yielded 15 bundles of cocaine.

The suspect was driving the vehicle.
