S-H-O-C-K-I-N-G! 9-years old Boy Flies Plane To Las Vegas!

US authorities are still trying to figure out how a nine-year-old boy from Minneapolis travelling alone, boarded a plane without a ticket and flew to Las Vegas.
This happened Thursday morning at St. Paul International Airport, Minneapolis.
Police said the boy was somehow able to get through three levels of security.

The flight crew reportedly became suspicious of the boy during the flight, and contacted police, who met them in Las Vegas when the plane landed.

Airport officials reviewed security footage and found out that the boy spent a good amount of time at the airport before boarding the plane.

CNN reports that the boy was at the airport the day before. 
He passed his time by taking luggage from a carousel, bringing it to an airport eatery and then ditching it, asking a server to watch the bag "while he went to the restroom."

Then the following day the child took the train to the airport, cleared security and nearly made it to Las Vegas without detection.

Police believe the boy is a runaway, and he was returned to his parents.
