Yes, there are rumours of his gangsterism as well as his sex abuse.
I do remember a story about him boasting of his links to contract killers and gangsters. Also when he ran a dance hall in Leeds in the fifties, he was well known for behaving brutally to people who messed about. Even without the more recent allegations, he doesn't strike me as being pleasant.
Also I was looking at the BBC News website and some reporter called Clifford Luton from the sixties and seventies has been arrested for downloading indecent images and historic abuse. I sort of vaguely recall the name, but was he one of the top reporters going back to the sixties as he is 87 now?
