Jimmy Savile abused one of his victims at Dewsbury and District Hospital, West Yorkshire Police have said.
The 15-year-old victim was abused more than 40 years ago, but only came forward to police after Savile died in October 2011.
Hundreds of allegations of abuse have come to light as part of Scotland Yard’s investigation into the presenter’s past, Operation Yewtree.
West Yorkshire Police are currently investigating 79 crimes involving 68 victims relating to Savile and West Yorkshire Police have confirmed that it is investigating 28 cases where abuse took place in hospitals – including one at Dewsbury, when the victim was 15.
The main location of the offences was Leeds General Infirmary, where Savile volunteered, with complaints from 23 victims. Two victims were assaulted at St James Hospital, Leeds, and two at High Royds Hospital, Menston.
A spokesperson from The Mid Yorkshire Hospitals NHS Trust, which runs Dewsbury and District Hospital, said: “We were made aware in December of the allegation by the police team conducting Operation Yewtree.
“This is one of a number of alleged incidents which were not reported at the time that have come to light as a result of the publicity surrounding this case. The allegation relates to events more than 40 years ago and approaches to protection of vulnerable people – both children and adults – have advanced beyond recognition in that time.”
