At least 17 undocumented immigrants were found in a tractor-trailer in southern Texas Sunday, authorities said.
A relative in Mexico tipped police in Edinburg that a family member had been trapped in a locked trailer at a Flying J Travel Plaza gas station along the U.S.-Mexico border, CNN reported.
The immigrants found alive in the vehicle were from Mexico, Guatemala, Honduras and Romania. The conditions of the 14 men and three women were not immediately known.
The tipster said their relative was with other immigrants and complaining of high temperatures in the trailer, according to the network.
Two Cuban nationals were arrested in connection to incident, Edinburg Police Chief David White said, adding that U.S. Customs Border Protection is investigating the case.
The discovery comes a month after more than 30 people were found inside a tractor-trailer in San Antonio. Ten people died of heat exhaustion in the botched human trafficking attempt.
James Bradley, 60, the driver of the trailer, was arrested and charged with smuggling the people.
