I know a school age teenager who I class as a friend who has been befriended by a man in his forties, the man has had a nasty accusation regarding a school age teenager in the not too distant past made about him. I have no way of proving or disproving this accusation its word againts word.

I dont know what to do with this although I know I must do somthing, I have a way of talking to the parents if need be, or do I talk to the teenager and hope they listen but I have no way of checking to make sure the teenager has listened and taken my advice.

As a parent I cant sit back and do nothing but I really dont know what I should do.
