An airline passenger carried a gun through the TSA checkpoint at Atlanta’s airport and carried it all the way through to his overseas destination, according to a report from Channel 2 Action News.

The news station reported that the Transportation Security Administration confirmed the incident with ABC News, saying the man and his firearm made it through the checkpoint at Hartsfield-Jackson International Airport on Jan. 2 and he boarded a Delta flight to Tokyo Narita International Airport.

ABC News reported that the owner of the gun informed airline workers of what happened “upon arrival” in Japan. Delta confirmed to ABC News that upon the customer’s disclosure, airline officials alerted TSA.

The TSA said in a statment: “TSA has determined standard procedures were not followed and a passenger did in fact pass through a standard screening TSA checkpoint with a firearm at Hartsfield-Jackson Atlanta International Airport on January 2. TSA will hold those responsible appropriately accountable."
