The letter accusing a BT customer of fraud is bogus, according to a learned reader of The Register. Matthew Garrett, a medical student at Cambridge University said: "The alleged letter from BT is a fake. "Putting it through a colour filter reveals that the BT logo in the top left corner and the bar code and footer have been scanned in and pasted on top of a computer-generated document. "Creases are also clearly visible around the staple region, but oddly enough aren't anywhere else on the page. "And as a final nail in its coffin, the background of the main page is full red, green and blue, a value that is highly unlikely to occur in nature since paper tends to be slightly off-white. "The rest of the page is plain and perfect white, which would only occur in a computer-generated image. "Hence it is fake. "If anyone can produce that with a scanner and a perfectly ordinary sheet of paper, I'd be greatly impressed. "My version of it is here (http://www-jcsu.jesus.cam.ac.uk/~mjg59/0800.jpg), and I know there's some other enhanced copies floating around," he said.

After his thorough job on this little number it looks like Matthew will have no problems sailing through his post mortem course. ®
