Junction City Authorities have uncovered about 830 pounds of pot during a weekend bust in northeast Kansas.
The Geary County Sheriff's Department said in a news release that a sergeant discovered the marijuana Saturday night after pulling over a tractor-trailer's driver for following another vehicle too closely on Interstate 70.
The release said the sergeant became suspicious after talking to the driver and received permission to search the vehicle.
The bales were found in the cab of the truck in a false-ceiling compartment.
The prosecutor's office said the driver was arrested but that no charges were immediately filed.
The release says the bust is one of the largest in the county's history.
