(CBS) – Three different men were allegedly caught with guns in their carry-on bags within a span of a few days at Chicago's two airports.

Kunal Singh stopped at a security checkpoint at O'Hare International Airport on Friday.

An unloaded handgun and a loaded magazine was in his bag, police said.

Saturday, 44-year old Leo Kurylo was arrested by TSA agents at Midway Airport with a semi-automatic pistol in his carry-on, authorities said.

Three days earlier, Aaron Anderson of Des Plaines was apparently caught trying to board a flight at O'Hare with a hand gun packed in his bag, authorities said.
