A Virginia man was stopped at Ronald Reagan Washington National Airport after TSA officers found a loaded gun in his passenger carry-on bag, authorities said.

Donald Gramling, 50, of Stafford, was cited Monday with carrying a weapon on airport property after TSA found a .40-caliber handgun loaded with five rounds and one bullet chambered inside his carry-on luggage.

Gramling had a Virginia concealed weapons permit and said he forgot that the firearm was inside the bag.

The gun and ammunition were confiscated, and Gramling was allowed to catch his flight to Montreal.
