TSA contacted the Allegheny County Police, who responded to the checkpoint, confiscated the handgun, and detained the woman.

Allegheny County Police arrested 31-year-old Kierra Allen and charged her with firearms not to be carried without a license. They say she did not have a valid concealed weapons permit.

Allen was arraigned, and then released on her own recognizance.

Police say they notified the FBI of the incident.
