FB account created with my email, what do I do?

So somebody created a FB account using my email. Having email control, I did change the FB account password, yet I cannot login into the FB account to delete it because the my location doesn't match to what FB used to see. So the account is now locked-out.

Yet, Where does their privacy stops and my rights start ? Creating linked accounts through social networks with spoof email didn't seem a problem so far, but between hacking attempts and info fishing, and legitimate mistakes, privacy and security are at risk.
