A Langley, B.C. man was arrested at the Sumas border crossing Tuesday after U.S. authorities found $6 million worth of high grade marijuana hidden in the floor of his cattle truck.

Edwin Roy Fuller, 39, was transporting beef cattle into the U.S. when he was selected for an intensive inspection, and border officials found hundreds of bags of "BC bud" in a hidden compartment.

To recover the stash, weighing 1,746 pounds and worth up to $6,000 a pound in the U.S. market, authorities had to dig through smelly cow dung and unbolt the door of the floor compartment.

"We will continue to be vigilant in our mission of protecting the homeland from terrorists and the criminal elements that would harm our society," said Area Port Director Pat Hinchey.

"And while it is not everyday we discover drugs hidden under cow flop, it does have its own unique sweet smell of success."

Eventually all the marijuana was packaged into 69 large boxes and placed back into the cow trailer for transportation to a secured repository vault.

Fuller was taken into custody on site by border officers and turned over to agents of the U.S. Immigration and Customs Enforcement (ICE) for his initial appearance in U.S. District Court in Seattle.

ICE is conducting the criminal investigation.
