MILWAUKEE (CBS 58) -- Transportation Security Administration (TSA) intercepted a handgun at Milwaukee Mitchell International Airport (MKE) on Friday, April 22.

According to a news release, during the routine screening of carry-on luggage, a TSA officer spotted the image of a handgun on the X-ray screen. The incident occurred around 5:30 a.m., and TSA officials immediately alerted the Milwaukee County Sheriff's Office. 

A deputy responded and issued a citation to the passenger, who had a concealed carry license. 

“Bringing a firearm to the checkpoint can have serious consequences and endangers other passengers,” Wisconsin TSA Federal Security Director Mark Lendvay said. “Responsible gun owners know where their firearms are at all time. Either leave your gun at home, or pack it properly with your checked baggage." 

This is the seventh firearm detected at MKE this year. A total of 23 firearms were detected at MKE security checkpoints last year.
