7News caught them on the road:

These are the two fuel bowsers in the Bullet Tree area shortly after they were intercepted by Customs before 6:00 this morning. Each of the trucks carries three thousand gallons of what is believed to be contraband gas and diesel.

Reports say they were intercepted coming out of a farm that is kind of a like a a smuggling free zone. A customs enforcement team impounded both trucks and instructed the drivers to head to the Headquarters in Belize City.

We met them on the highway where each bowser had a customs escort in tow. We could tell that both of the bowsers were quite old, and one of them had the faded logo for CP gas.

But the owner of that company showed us that he had transferred ownership of the truck two years ago to Antonio Novelo.

As the vehicles are now sealed in customs - he will have to explain the origin of the fuel, and why his truck was in that remote area where there are no gas stations.

Reports say that as many as two to three bowsers come through the same area weekly - which, if they are moving contraband fuel would expose a massive and thriving black market and huge losses for the importer, PUMA.

We were unable to reach Antonio Novelo for comment.

Sources tell us that this farm land in Calla Creek - which is a smuggling hotspot is also used for the state sanctioned illegal export of cattle into Guatemala.

Notably, there's a police checkpoint in Bullett Tree - but, sources tell us, the bowlers pass through regularly, without impediment.
