Weird Index Page Listing

Hope it's not link hijacking

Paranoia I hope. I have a shopping directory that does well in google, but I then notice I now had two index pages in google.

1st page - www.mysite.com
2nd index page - www.mysite.com?source=www.anothersite.co.uk

should i be worried about this and how did that happen?

I have never even heard of this site and can't see why they would do it, I assume this is a redirect? Why would they do it?

If and when Google realises that those URLs return identical content, they should be merged. Given that your preferred listing comes first, that is likely to be the URL that remains in Google.
