"Dear Citibank UK Customer! For security purposes your account has been randomly chosen for verification... "

If you have received this email, please remember that it is very common for these email scams to be redistributed at a later date with only slightly different content or the same but with the fake page(s) hosted by a different provider. Also, once you have received one of these hoaxes, it is also common place to receive at least another one and usually a day or two after the first, although not necessarily from the same apparent sender.
