I need to contact facebook immediately?

[the beatles are awsome<3]

this very old looking guy in his 50's to 60's recently contacted me that I didn't know and asked me very inappropriate things and asked me if "I was horny" I'm a young girl who is only 18 and this was not okay so I threatened to report him to facebook and the police, and he said "bye bye" and deleted his facebook. I'm really scared that this guy is A child molester, and if that's the case he shouldn't be on the streets, but I have no way to report him, and I only know his name and that he lives in the united kingdom, and I have his picture. How do I go about contacting facebook so that they could make sure he doesn't get another one, or maybe they could contact the police. But I don't think me contacting my local police would do any good, because I live in the united states and it will be very hard to find him.
