I wonder where the 'purple' bit of his nickname comes from .. it can't be his skin because that's brown .. does purple translate as 'dodgy' in Liverpool ?.. I expect he was an alcoholic because of the strange sweating at a strange time mentioned, he could have also been homosexual .. big men would find it harder to come out of the closet because they're supposed to be tough so he'd creep'd about asking men if he could touch them .. no reports of him actually attacking anyone though .. interesting. The police are clearly already aware of him, I think the presenter is correct in wondering if a bit of racism is also involved in this man becoming an urban legend ..
