LONDONDERRY, N.H. (AP) – Police arrested the driver of a federal vehicle, charging him in a road rage incident.

Michael Slack, of Enfield, faces a charge of criminal threatening and carrying a loaded gun without a license.

Police stopped Slack, 23, who was driving a sedan with U.S. government plates, after a motorist called Tuesday to report an erratic driver waving a pistol out a window.

Several officers gathered to stop the car on Route 102. Police said they found a loaded pistol a bag of clothes in the car. It wasn’t immediately clear whether Slack was a government employee. He was held overnight and arraigned Wednesday.
