Grand theft marijuana: Carjackers in California steal truck hauling half-ton of cannabis

A police helicopter spotted people unloading the trailer and throwing large bags into the backyard of a home

POMONA, Calif. — Authorities have arrested three men they say carjacked a big-rig hauling half a ton of marijuana and led them to a pot-growing operation at a Pomona home.

Authorities say the whole thing may have been a drug deal gone wrong.

The Riverside Press-Enterprise reports the truck was stolen Friday in Pomona. A short time later, a police helicopter spotted people unloading the trailer and throwing large bags into the backyard of a home.

Officers arrived and found that the trailer and the bags contained about 1,200 pounds of marijuana.

Some 240 pot plants were found growing inside the home.

Three men were arrested in connection with the carjacking and pot possession. The two victims also were arrested on suspicion of possessing marijuana for sale.
