A transcript of the interview between Pollard and the former director-general George Entwistle refers to examples of the comments including one person who wrote: "One of my best friends in 1972 was molested by this creep Savile. He was never the same again.
"Killed himself in 1985. How's About That Then?"
Another person wrote: "He was a paedophile. You may not like the truth but he was. It will all tumble out now."
The BBC has released 19 witness statements into the Jimmy Savile investigation, including Newsnight presenter Jeremy Paxman who said: "I have to say, I think we make a problem for ourselves by running away from this story."
He added: "We wouldn't even tackle a b***** story that was about our own programme. This is pathetic."
