OMAHA, Neb. (AP) — Authorities say two men from California have been arrested after nearly 400 pounds of marijuana was found in a recreational vehicle in Omaha.

The Douglas County Sheriff’s Office says the men, from Fontana, California, were taken into custody early Friday after a traffic stop in the city’s south side.

Authorities say a deputy’s dog indicated the odor of drugs in the RV. Twelve large boxes containing nearly 400 pounds of packaged marijuana was later discovered in various areas of the vehicle.

A third man in the vehicle fled during the traffic stop. Authorities have been unable to find him.
