An 11-year-old boy boarded a plane in Manchester headed to Rome without a ticket or passport. Airport authorities are investigating how he managed to get through security undetected.
In a statement on Wednesday, Manchester airport management called it an "extremely serious matter" which is being investigated by officials of the airline and the airport. It says that some staff had been suspended from duty, but did not say how many.
The boy passed through security without being checked, before making his way on to the Jet2.com flight Tuesday.
