Names

Is there a way to find out a persons name who is saying libelous and personal things about you? Such as giving out your full name, address, town, and other landmarks around you. Besides always harassing me, he has hacked into my computer, stalked me online, followed me to other areas, and read my emails. What do I do about this person? I don't know their real name, but several that they use on Network 54. I also know their Yahoo email.
