Authorities say an unloaded handgun and ammunition were found in a carry-on bag at an airport in Des Moines.
The Transportation Security Administration says the gun was detected at a screening checkpoint Wednesday at Des Moines International Airport. The unloaded handgun, several magazines and ammunition with 42 rounds were found in a bag belonging to John Thompson, a U.S. Army captain from Virginia.
The 33-year-old Thompson told authorities he didn't know the items were in the bag. He was arrested and charged with an airport regulation screening checkpoint violation.
Firearms and ammunition are prohibited in carry-on baggage, but can be checked in at the ticket counter in a locked container.
This is the second firearm found this year at a screening checkpoint in Des Moines.
