BILLINGS, Mont. (AP) — A 29-year-old Florida man has pleaded not guilty to a federal drug charge after authorities say he was travelling with 78 pounds of meth on a Montana highway.

Authorities say it was the largest amount of meth ever seized in a traffic stop in the state.

Nicholas James Imhoff was returned to custody after appearing Monday in federal court in Billings.

Authorities say he was travelling in a van rented in Las Vegas and the drugs were found under floor storage compartments in garbage bags.

Imhoff told a state trooper that he was headed to North Dakota for work.
