I've seen this scam 100 times. It's not even London based. These are scammers from Nigeria. I saw a special on TV once about these scammers in Nigeria. You should see the "internet shacks" they send this crap out from. On the special, the Nigerian police raded one of these shacks.., and caught two guys in the act of typing a bogus email to launder money. It's really sad too. These Nigerian low-lifes even have well known Nigerian musicians that write songs promoting "scamming American's".
