A Virginia man was stopped at Washington Dulles International Airport for attempting to bring a loaded gun onto a plane.

According to Metropolitan Washington Airport Authority Police, Albert N. Henderson Jr., 52, of Warrenton, was trying to board a flight to Houston on Sunday when a checkpoint X-ray machine revealed that he had .22-caliber revolver and ammunition in his carry-on bag.

The gun and ammunition were confiscated. Henderson was charged with possession of a dangerous weapon at the airport, a misdemeanor.

Henderson was allowed to catch his flight.

Passengers are permitted to travel with firearms in checked baggage if the guns are properly packaged and declared. Firearms must be unloaded, packed in a hard-side case, locked, and packed separately from ammunition. Travelers can be fined up to $11,000 if they are caught with prohibited items at the airport.
