Alison Smith told BBC News that she will speak to the police tomorrow about allegations she is making about the peer's behaviour.
Tomorrow I will be talking to the police and I think the trial by media, probably it is time for that to finish.
I was told by Baroness Ros Scott that he had to leave because of his unacceptable behaviour, which I had raised with the party several times.
Ms Smith said the decided to "blow the whistle" because the peer had started to become involved again in a training event.
"We were told he was not going to make a comeback, now here he is, turning up all over the place," she added.
