I was away with no internet when this story broke. I have to agree with Linda, DLT was quite local to my home town and regularly there. I have never heard anyone say anything bad about the guy (unlike Savile, who was well known at Stoke Mandeville of course, also not far from me).
I cannot see for a minute DLT being involved in anything sordid. I also get the impression that they just looked for someone with a similar cv and era to Savile - or perhaps someone else decided to implicate him. If I am wrong I will apologise but for now my sympathies are entirely with Mr. Travis.
