This thread has served its purpose. My eternal thank to Hiniguel for trying his best to get to the bottom of this, Much of it was conjecture but some of it led us on the trail t0 find the thief/hacker. Hinigel is to be regarded as a hero. I doubt any of the rest of you would have spent half a million pounds trying to get other people their money back. Gray hat's off to you Hiniguel.
