how to report a fraud and identity theft in Yahoo?

This guy is at it again. His email address is:
Now, he got hold to my gmail account by fowarding everything to his email address.

I guess he got my email address password as well as all my other dedicated server login .

Is there a way i can report him to yahoo?

He used the same email address when he last stole my domains in godaddy via phishing attempts.
any helps are appreciated.
