The bear was lost or abandoned more than a year ago and probably only came to light when airport personnel did their periodic clean-out of the lost belongings storage room. Since it was a more interesting item than the average raincoat, they have attempted to locate the owner. Given the elapsed time, there may no longer be useful video available and, even if there is, that is a very labor intensive and costly way to go about identifying the owner. Media publicity is cheaper. The bear has received extensive publicity in Britain and yet apparently no one has come forward to claim it. I conclude that:
1) the owner has since died, or
2) the owner is not in Britain and is unaware of the publicity, or
3) the owner does not want to be found, or
4) it is [as was suggested many pages back] a publicity stunt
