I hope someone has told the authorities that this aircraft is safe. BBC News suggests the alert is still on.
It's completely and utterly beyond my comprehension that a pilot should cause an airfield to be informed of his planned arrival, then change his mind and not warn them - if that really is the case this time. But I've seen it happen more than a few times... resulting in police turn-outs, searching of hangars in the middle of the night, etc.
