Ex-BBC DJ Jimmy Savile sexually assaulted victims aged five to 75 in NHS hospitals over decades of unrestricted access, investigators say.

He assaulted patients in bed, and claimed to have abused corpses, reviews into his conduct on NHS premises found.

The Leeds investigation found:

• Sixty people came forward to say they had been abused between the ages of five and 75, including staff

• The offences ranged from lewd remarks to sexual assault and three cases of rape and took place between 1962 and 2009

• Only nine victims told members of staff. There were a further eight female victims who met Savile at the hospital, but were not patients

• Savile had a well-known fixation with the dead and the report contains allegations he posed for photographs and performed sex acts on corpses in the hospital mortuary

• While there is no way to verify the claim, Dr Sue Proctor - who led the Leeds inquiry - said there is no doubt controls on access to the mortuary were "lax"

• Patients, including teenagers recovering from surgery, were abused in their beds

• A 10-year-old boy was sexually assaulted while he waited on a trolley for an x-ray on his broken arm

• A number of organisational failures over the years enabled Savile to continue unchallenged

• The situation allowed someone "as manipulative as Savile to thrive and continue his abusive behaviour unchecked for years"
