libel on facebook

Hi just want to ask if I can file a libel case that happen on facebook?

I have a friend whom I owed money from. I still owe him the money but what he did, he posted a picture of me with captions stating to pay him the money and he even send that picture to some of my family members and to our common friends. He even created another fb account with a different name but with some of my picture including the same caption. He added some of my schoolmates in highschool. My schoolmates send me a copy of the message and asking me who is the person defaming me. I was really embarrassed and felt harassed.

Please advise me on what I can do to this person.

Thanks

if you can prove that it was him who made the posts then you can file a complaint of libel. you can go to the cyber crime divisions of the pnp or ngi for assistance.
