Neither the child's parents nor airport workers noticed the curious youngster had sneaked onto the ramp until the child went through baggage X-ray equipment, Aftenposten reported Thursday.

After climbing onto the ramp, the child went out of sight, through a chute and through scanning equipment, the report said.

"It's unfortunate that a child could get into the system like this," ground services official Thor Hagen told reporters.

Officials said the child was reunited with his parents minutes after being found and airport safety procedures were being reviewed.
