Something very suspiscious going on here - my BS antennae were twitching before I even I read:
"The incident was said to have happened on a five-and-a-half hour overnight flight from Lagos, Nigeria to Heathrow in London on April 10, 2011" and
"The hearing in Reading, Berkshire, was told by Kirsten Barry, representing BA, that the £65,000 cash was counted twice in front of the customer and an accountant in Nigeria. Both made sworn statements to police, she said.
It remained with the passenger throughout the journey, including airport security in Nigeria and West London.
The passenger travelled from Heathrow to a hotel in upmarket Mayfair, London, when he realised half his cash was missing. He was due to fly out to Switzerland to purchase watches."
I can see this as some sort of derivative of a scam, not sure whom is being scammed yet - the Flight Attendant, someone in Nigeria, British Airways or even the British justice system. At the very least we have a couple of perjury cases come out of this as well as a possible unlawful dismissal. Time will tell.
