A 19-year-old Lubbock man was arrested Friday after deputies stopped him and found more than 400 pounds of marijuana in his auxiliary fuel tank.

The Fayette County Sheriff’s Office said Sgt. Randy Thumann and his K-9 partner Lobos stopped a pickup being driven by Gilberto Torres, Jr. on Interstate 10 around 11:50 a.m. Nov. 4. Torres displayed “extreme nervousness” and Thumann was able to disprove his travel itinerary, the sheriff’s office said.

Lobos and Thumann conducted an exterior sweep of the vehicle, and Lobos alerted to the auxiliary fuel tank in the bed of the truck. The tank was examined, and approximately 468 pounds of marijuana was removed from inside the tank. The sheriff’s office estimated the value of the marijuana at $234,000.

Torres was arrested and taken to the Dan R. Beck Justice Center.
