Probably a genuine warning

The email states that if customers did not purchase the item they should click on the link provided to obtain a refund. Once redirected to a web page they are asked to fill out their card and other personal details. This is a spam email with links to a malicious web page that is being used to harvest personal details, possibly in order to access victim’s bank accounts."
The above is a copy of an 'alert' received from 'Dorset Alert' - an outfit sponsored by Dorset Police amongst others. Naturally no WAMUG member would fall for such a fraud but their friends and family might. I'l be interested if someone says that this is itself just a frightener.
