Jimmy Savile (1926–2011) was an English DJ, television and radio personality who was well known in Britain for his eccentricities and, at the time of his death, was generally respected for his charitable work. He was knighted in 1990. In September and October 2012, almost a year after his death, claims were widely publicised that he had committed sexual abuse, his alleged victims ranging from prepubescent girls and boys to adults. By 11 October 2012 allegations had been made to 13 British police forces, and this led to the setting-up of inquiries into practices at the BBC and within the National Health Service.
On 19 October 2012 the Metropolitan Police Service launched a formal criminal investigation, Operation Yewtree, into historic allegations of child sexual abuse by Savile and other people, some still living, over four decades. It stated that it was pursuing over 400 lines of inquiry, based on the claims of 200 witnesses, via 14 police forces across the UK. It described the alleged abuse as being "on an unprecedented scale", and the number of potential victims as "staggering". By 19 December, eight people had been questioned as part of the investigation. The Metropolitan Police stated that the total number of alleged victims was 589, of whom 450 alleged abuse by Savile.
The report of the investigations undertaken jointly by the police and the National Society for the Prevention of Cruelty to Children (NSPCC), Giving Victims a Voice, was published on 11 January 2013. It reported allegations covering a period of fifty years, including 214 alleged acts by Savile which, though uncorroborated, have been formally recorded as crimes, some involving children as young as eight. The report states "within the recorded crimes there are 126 indecent acts and 34 rape/penetration offences." Alleged offences took place at 13 hospitals as well as on BBC premises, according to the report. In October 2013 it was announced that inquiries had been extended to other hospitals. On 26 June 2014, the Secretary of State for Health, Jeremy Hunt, reported on the findings of the investigations led by Kate Lampard. He said that Savile had sexually assaulted victims aged between five and 75 in NHS hospitals, and apologised to the victims. Further investigations, in hospitals and elsewhere, led to additional allegations of sexual abuse by Savile.
