My facebook group was hacked

Hello,

Someone hacked into my gmail account, and then my Facebook account, and sent Facebook messages to some of my friends, pretending to be me. These messages was sexually explicit and harassing. I have no idea who it might be!

Is it possible that I can trace the person, and then block them?

Where can I report this, or what steps should I take, because I feel unsafe and threatened, and afraid that it might happen again.

Thank you


Configuration: Mac OS X / Safari 534.52.7
