A Transportation Security Administration screener spotted the gun about 7:50 a.m. Tuesday while X-raying a bag belonging to a man who was identified by police as Jose Perez, of Palos Heights.

TSA personnel detained Perez at the airport for Chicago Police, who seized the handgun. Prosecutors charged him with attempting to carry a concealed firearm in an airport, a misdemeanor.

Perez has a valid firearm owner’s identification card, but that does not entitle someone to carry it on board a plane.
