BOISE -- Transportation Security Administration officers at the Boise Airport had to stop two different people from carrying a loaded gun onto a plane in less than a week.

The first incident happened Friday morning when a man headed to San Diego tried to pass through security with a Ruger SP 101 revolver loaded with five rounds of ammunition. The man was cited by Boise Police for having a firearm at an airport checkpoint.

According to the TSA, history repeated itself Tuesday morning, when a man put a bag containing a .357 Taurus revolver loaded with six rounds through the security X-ray. The officer monitoring the machine spotted the outline of the gun and notified Boise Police.

An officer confiscated the revolver and cited the man, who was headed to Las Vegas.

"Passengers are 100% responsible for the contents of their carry-on and checked baggage," TSA Federal Security Director for Idaho Andy Coose said in a press release. "The requirements for air travel are different than for other types of travel. The best piece of advice I can give is to carefully check your bags before you pack them to ensure you are aware of all the contents of your luggage prior to coming to the airport."

The latest incidents were the 12th and 13th firearms discovered in carry-on baggage at the Boise Airport this year. Last year, a total of 14 guns were found.

Officials say there was no disruption to the Boise Airport, and it does not appear the Tuesday and Friday incidents were connected.

Firearms, gun parts and ammunition are banned from carry-on baggage, but can be transported in checked bags if they are unloaded, properly packed and declared to the airline. Anyone who tries to bring a gun through the security checkpoint can face charges and a civil penalty that can range from $3,000 to $7,500.
