The Transportation Security Administration fired a woman responsible for screening passengers’ bags after she missed a loaded handgun Sunday morning at Hartsfield-Jackson International Airport, Channel 2 Action News reported.

Katrina Jackson of Alabama noticed her .38-caliber handgun when she later looked for her passport and immediately informed officials, according to a police report obtained by Channel 2.

TSA issued a statement to the news station. “This egregious mistake was unacceptable and the officer who was still a probationary employee was immediately and permanently separated from federal service."

The woman self-reported to police and officers showed up at the gate to confiscate her gun and bag.

Jackson was charged with illegal possession of a handgun when she said she didn’t have her permit on her.

Screeners at the airport have prevented 48 guns from going through security so far this year, Channel 2 reported. Last year, 198 guns were found at checkpoints, which is more than any other airport in the United States.
