Kelly says that the woman told her about the "prominent man" in the Irish media: "He raped me 40 years ago. I can still smell him on me.”
The broadcaster says that she also had her own lucky escape from the same sex pervert.
"I’ve met him twice, but both times in a group setting. He messaged me immediately after the first meeting by Twitter DM," she wrote in a long message on social media.
“He was very complimentary - ‘You are very talented, we must meet for coffee’
“I declined, something about him made me uneasy. I was polite, though. I was friendly. Many, many messages came, I declined other invitations.
“I met him again, we were at [the] same event. I spoke to him briefly but didn’t engage - I was with friends.
“More messages came – ‘Who do you think you are? You’re becoming a national joke’ late at night followed by, ‘Please forgive me I don’t know what came over me’ the following morning."
She added: “I spoke to friends, they all had stories they’d heard, ‘Be careful he’s violent - he beat his wife’.
“He had a car back in the day, he offered girls lifts home – the passenger door handle was broken they couldn’t get out.’ ‘I have a friend he did the same to, he plagued her’. The messages, bizarre in their over familiarity, stopped eventually and I half forgot.
“Then this woman approached me. ‘I can still smell him on me - there were lots of us,’ she said.
“And I believed her. I’ve thought a lot about her and am shaking writing these tweets but I believe that woman, that this man raped her and likely others."

A woman I dont know approached me recently about a prominent man in the Irish media "He raped me 40 yrs ago. I can still smell him on me" she said visibly distressed.
I don't know this man well - Iv met him twice though both times in a group setting... #IrishWeinstein
