A test of screening procedures?

"Gun, ammunition confiscated from air passenger," from [1] CBC News, June 17 (thanks to APA):

A man was arrested at the Calgary International Airport Tuesday after a handgun was detected in his carry-on luggage.

Security officers in a pre-boarding screening area at concourse D noticed the gun inside the luggage and alerted police just after noon Tuesday.

Police arrested the man without incident and seized an unloaded, small calibre handgun and several rounds of ammunition from the bag, said Calgary police. They believe the man was flying to Saskatoon.

Ziad Mohamad Jeha, 30, of Calgary, has been charged with possession of a weapon dangerous to the public peace, possession of a concealed weapon, possession of a weapon without a permit and possession of a restricted weapon with readily accessible ammunition.

Calgary police said the suspect is known to them.

That's an interesting last paragraph.
