Man accidentally leaves gun in carry-on bag: TSA agent accidentally fires gun during check.

Can we get the private screeners now?

(CNN) -- Some travelers sleepily making their way through airport security in Atlanta Sunday morning got a startling wake-up. A gun detected in a carry-on at a checkpoint at Hartsfield-Jackson International Airport was accidentally fired by an investigating officer around 9 a.m. Sunday, according to a police report.

Transportation Security Administration screeners reported the gun to Atlanta police officer N.J. Phillips, the officer wrote in an Atlanta Police Department report. The gun's owner was telling Phillips how to clear the loaded .22 Magnum revolver when it was accidentally discharged, Phillips reported. "The weapon was pointed down towards the screening table."

"I was grazed by a pellet fragment on the left side of my face," Phillips wrote. "However, there were no visible injuries."
