Sex abuse survivor speaks out: 'You've taken my life so far, but you won't take another day.'
The Radio 1 DJ died aged 84 in 2011, just a year before allegations that he had sexually abused children were broadcast in an ITV documentary.
Reports on Leeds General and Broadmoor psychiatric hospital are the most detailed of all, with the findings making 'shocking reading' according to the Department of Health.
From the Leeds investigation, it was revealed that Savile allegedly performed sex acts on corpses in the hospital mortuary, as well as raping several other people on the site and committing dozens of other assaults.
Jimmy Savile's victims told: 'You're lucky he paid you attention.'
One 16-year-old victim told of how she was abused in a basement at Leeds hospital, but was laughed at when she reported the incident.
'I think you just feel dirty, you feel ridiculously stupid,' she told Radio 4.
The Broadmoor report found that Savile was 'narcissistic, arrogant and lacking in any empathy.'
It describes how the DJ would watch and make inappropriate comments as patients stripped and showered, and also abused vulnerable people of various ages at the hospital.
Other hospitals that have been investigated in relation to the Savile case include Great Ormand Street, Portsmouth Royal, Leavesden Secure Mental Health and many others.
