Got a bit of a dilemma.
After watching the jammy Saville doc last week I remembered that earlier this year a current v minor TV presenter several times touched my leg at a charity dinner. It was in a busy room and I was too shocked/confused to ask him to stop! I had only just met him and was three months pregnant so wasn't flirting and I believe his behaviour was sleazy if not predatory.
This person has already been reprimanded for inappropriate behaviour at work in the past so I believe he has form.
My question is, should I tell his employer even though he wasn't attending in a work capacity? Or should I just email him and say that I am on to him?
I don't want a fuss by the way and it was possible that he was just being "friendly" 
but it occurred to me that Saville got away so long because of women minimising incidents like this one.
