PRESIDIO, TX — U.S. Customs and Border Protection Officers seized over 125 pounds of marijuana at the Presidio Port of Entry.

Officials said a man in a pickup was trying to enter the U.S. and seemed nervous during routine questioning.

After searching his vehicle, a drug-sniffing dog alerted them to the gas tank where border agents found two large metal boxes.

The boxes were filled with compressed marijuana valued at more than $100,000.

The driver is from Mexico and was arrested.
