ORLANDO, Fla. — A passenger tried to bring a loaded gun in a carry-on bag at Orlando International Airport causing a long back-up at checkpoints during the Christmas holiday rush.

Transportation Security Administration spokeswoman Tari Koshetz told The Associated Press the passenger was carrying a Ruger with a separate magazine loaded with 10 rounds of .22-calibre ammunition. The incident caused a backup at the busy airport early Tuesday morning.

Koshetz says it was the 91st weapon intercepted by TSA officers at Orlando’s airport this year.

Orlando police spokeswoman Michelle Guido tells local news outlets the passenger has a valid Florida concealed weapons license. Federal law, however, prohibits passengers from carrying weapons through airport checkpoints. Guido says the passenger will be charged with carrying a concealed firearm in a place prohibited by law.

The passenger’s name wasn’t immediately released.
