Edinburg police make a big marijuana bust and detained an suspected drug smuggler.

Chief Quirino Munoz says the suspect was using a tractor trailer, called a "belly dumper", to haul the drugs when he was spotted at the Flying J Truck Stop, on north US 281.

Those 18 wheelers, he said, are normally used to haul caliche or gravel and have doors that open underneath.

"For some unknown reason, the bottom doors came open and apparently the bundles of marijuana fell out and that's how we got the call," said Munoz.

Police arrested the truck driver after they chased after him for a short while.

They seized about 150 bundles, weighing about 2-thousand pounds.
