It's hard to believe isn't it? And most folk who were brought up seeing him on telly probably do not want to beleive it.
But we don't know yet what type of offence, if any he's being questioned about. Is it about child molesting? Is about inappropriate behaviour towards young women or men? Or is he totally innocent? I don't know, but the whole thing is really unpleasant, whatever the outcome he is tared by the brush now, and his professional and possibly his private life is over.
I met him once, about 15 years ago, spent about three hours with him, we working at an event together in Bray, he was completely charming and a joy to talk too, i liked him very much, I really hope he is innocent.
