somebody threatened me on facebook, what do i do?

ok so this guy that i dont really know but thought i did because he had 1 mutual friend as me (btw i have known said mutual friend for years) and he started messaging me nasty pics of himself. when he did this i logged off of facebook for a long time, and then he sent me another one that said that if i dont give him 3 pics of my private parts by a certain date the he would send what looks like nude pics of me to every single one of my friends on facebook! and he said that blocking him would do nothing because he would make another account and do it from that one! but i blocked him anyways and then i deactivated my account! since i deactivated my account (and i blocked him) can he still send those fake pics to my friends? please help!! (btw, there are no nude pics of me on facebook, i'm not a whore XD, and so far i dont think he has done anything)

what this guy is doing is very illigal. copy proof that he sent these messages and try to report abuse (i dont know if u can do that on facebook) if possible try to contact some kind of authorities. What this guy is doing is, i think, called sexual abuse. do not let this guy get away with it. YOU NEED TO COPY EVIDENCE OF HIM SENDING THOSE MESSAGES!!!! hopefully if you do not have them facebook has logged them for cases just like this. WHAT THIS GUY IS DOING IS VERY VERY ILLEGAL ESPECIALLY IF YOU ARE UNDER 18!!!!!!
