Britain's late TV presenter and radio host Jimmy Savile sexually abused hundreds of people and carried out more than 30 rapes, police said Friday, as they unveiled a report exposing "vast, predatory and opportunistic" abuses across six decades.

Nearly three-quarters of his victims were children, the report said, with the youngest only 8 years old. Most but not all were female.

Since the inquiry was launched three months ago, about 600 people have come forward to provide information, 450 relating to Savile, London's Metropolitan Police said.

From this, 214 crimes have been recorded, including 34 of rape or penetration, across the country.

The earliest claim against Savile, who was still a household name when he died in 2011, dates from 1955 and the latest from 2009, when he was in his 80s.

Savile used his celebrity to "hide in plain sight" as he opportunistically preyed on the children and young people with whom he came into contact as he presented BBC children's show "Jim'll Fix It" and music show "Top of the Pops," the report said.

Dozens of offenses on BBC premises have been reported across a 40-year span between 1965 and 2006 -- the last at the final recording of "Top of the Pops."

Fifty allegations against Savile relate to hospital premises, including hospices, the report said. Another 14 relate to schools, including a reform school he visited regularly between 1970 and 1978.

The scale of his abuse is believed to be unprecedented in the UK, it said.

The report by London's Metropolitan Police and a child protection charity, the NSPCC, titled "Giving Victims a Voice," brings to a close a sordid chapter.

Police set up Operation Yewtree to investigate sexual abuse claims after a documentary by broadcaster ITV in October unleashed a flood of allegations against the star, who before that was seen as an eccentric but charismatic man who raised millions of pounds for charity.

The investigation had three strands: one involving complaints against Savile alone, another termed "Savile and others" and a third involving only others. The publication of the report ends the first strand of the inquiry.

However, investigations continue into allegations made against the other suspects, some linked to Savile and others not. A number of arrests have been made.

"It paints a stark picture emphasizing the tragic consequences of when vulnerability and power collide," Commander Peter Spindler, of the Metropolitan Police, said of the report.

"Savile's offending footprint was vast, predatory and opportunistic. He cannot face justice today but we hope this report gives some comfort to his hundreds of victims, they have been listened to and taken seriously. We must use the learning from these shocking events to prevent other children and vulnerable adults being abused in the future. They will get a voice."

The BBC, whose reputation has been tainted by the affair, said it would continue to work with police to investigate the claims.

"The police report into Jimmy Savile contains shocking revelations," a statement said. "As we have made clear, the BBC is appalled that some of the offences were committed on its premises. We would like to restate our sincere apology to the victims of these crimes."

The BBC set up three inquiries of its own amid questions about how Savile's abuses went undetected for so long. One is looking at the culture and practices within the BBC and another at its handling of past sexual harassment claims.

The third, which reported on the broadcaster's decision to drop a program investigating allegations Savile in late 2011, slammed senior management as "completely incapable" of dealing with the crisis that erupted.

The BBC's botched handling of the affair forced the director general, George Entwistle, to resign.

The UK Department of Health, which is conducting its own investigation into the access Savile had to hospitals and other institutions, said the police report "highlights the shocking scale of offending by Jimmy Savile over five decades and shows the need to learn lessons from his crimes."

With the police review concluded, civil claims are likely to be brought as some victims seek compensation for the abuse they suffered at Savile's hands. About 73% of them were younger than 18 when they were targeted.

Four-fifths of the victims were girls and women, the report said. The majority of the victims were between the ages of 13 and 16 at the time of the abuse, and the oldest was 47.

Of the 34 reported offenses of rape or penetration, 26 victims were female and eight were male, police said.

"There is no clear evidence of Savile operating within a paedophile ring although whether he was part of an informal network is part of the continuing investigation," the report added.
