One passenger, ticketed to Philadelphia, was found to be wearing a plastic knife on a string around his neck, concealed beneath his clothing. Another, headed for Los Angeles, had a knife inside of his carry-on luggage. Both knives are prohibited by federal law from being carried aboard U.S. aircraft.
The passenger with the knife around his neck told security officials it was for his personal protection. Screening agents spotted the knife using the Advanced Imaging Technology body scanner, which is designed to detect metallic and non-metallic items on a passenger.
The knives found Thursday are the latest in a long line of weapons incidents at Salt Lake City International Airport in 2013. Only the night before, a passenger headed to California was caught with a handgun in his carry-on bag. It was the tenth firearm detected by agents at Salt Lake City's airport this year. Just 20 firearms were detected in all of 2012.
The TSA seeks to remind passengers that all firearms and sharp objects are prohibited from being carried or stored in carry-on luggage. Some restricted items may be carried in checked baggage, however. (Click here for a list of prohibited carry-on items)
