Portuguese national, 38, arrested at Heathrow after a major security breach
Alleged to have broke through security fence and locked himself into a 747
British Airways passenger jet parked at engineering base at time of breach
Police confirmed incident and said it was not believed to be terror-related
A source said that it was impossible for security staff to get to him because the bomb and bullet proof cockpit doors are designed to protect the pilot and co-pilot should a terrorist try to take over the plane in mid-flight.
'It was a very difficult and complex situation and in the end the fire brigade had to be called to the plane and carried out a long and very protracted operation to get into the cockpit from outside.
'Eventuallly they managed to gain access to the cockpit and police were able to storm in and arrested the intruder,' said the source, who asked not to be named.
