The Georgia Bureau of Investigation says a multi-agency squad has seized more than $1.6 million in a joint narcotics investigation that spanned the country.

The bureau tells WSB-TV in a story Saturday that agents arrested 12 suspects in Georgia and Louisiana in connection with the trafficking of marijuana.

Agents said they seized about 100 pounds of marijuana with a street value of $500,000, 10 vehicles, about $1 million in real estate, 50 firearms, about $120,000 cash, and about $20,000 in drug assets.

The arrests were made on Feb. 17. Agents determined that the marijuana was grown in Mendocino, Calif., and then transported to Douglasville through New Orleans.

They said mid-level dealers then distributed the marijuana into Atlanta and the surrounding areas.

More arrests and seizures are anticipated in the investigation.
