Someone is talking to colleagues and friends using a fake Facebook account in my name

Hi all, I 25f just realized someone created a Facebook account in my name and has been talking to people as if it's me. And some of these people are not even my friends, they are colleagues from work. I know this person who has been threatening me for a while now. But he lives in Saudi Arabia. Please tell me if can do anything about it. He is trying to hurt me.
