The Border Patrol discovered 20 immigrants locked in a truck container at a checkpoint near El Paso, AP reported.
The discovery came a day after 16 undocumented immigrants were rescued from a trailer in Edinburg and less than a month after 10 people died and others were injured aboard a truck due a lack of ventilation.
The immigrants from Mexico, El Salvador and Guatemala were in good physical condition when they were found Monday in Sierra Blanca, West Texas, on an Interstate 10, according to a spokesperson for the Border patrol quoted by AP.
The driver, identified as Irving Hernandez, known as "Rueda," (meaning "Wheel" in Spanish) was arrested for people smuggling and taken to El Paso jail.
