Words from our dearest friend who was affected very recently. She is in her mid 80s now.
A few days ago the telephone rang and a certain DCI James Galbraith from the Metropolitan Police wished to tell me that my credit cards had been tampered with, a lot of money had been withdrawn and would I help the MP to catch the thief? The first thing, of course, was to check on the veracity of his identity which I did by ringing 999 and asking to speak with DCI Galbraith, This done I started to help him in any way I could. A courier came and took my credit cards away; Galbraith was very worried about any jewelry and money in the house, but I told him they were too small to be worried about. The idea was to run a scam to catch the thief by my going to three banks and withdrawing £5000 at each, and then go home. (She was also told not to tell anyone including her son as it might jeopardise the whole sting operation) I told him what I would be wearing, but no the order of bank visit. Luckily for me I chose the Halifax where I am not known at all, which may have helped the cashier to be vigilant, although later he told me he could tell from my eyes that I was not telling the truth when asked why I needed so much cash. He sent for the police, who came very quickly indeed and the whole story unravelled. End of scam!
The police drove me home where I had alerted Bob (my son) to be; we cancelled the credit cards, and discovered they had been very little used; the small amount of money was immediately refunded by both banks. So I was very lucky, but the dent to my self confidence, not to mention my self esteem was, as you may assume, considerable.
