Facebook hacking

my boyfriend had an attempted hacking yesterday and he is convinced it is this guy who likes me. This guy is taking IT at A level and has said multiple times that he can hack an account. I talked to him saying my friend had an account she couldnt get into as bait. He said he could get into it but it was illegal and refused to. What should we do? We know its him but we have no evidence and he cant keep accessing our private messages and my boyfriends profile.

Go to the facebook creator at the bottom. Explain to them what happened and also block him from your account. They will help you. And the block works. He can't access your account in any way!
