Jimmy Savile could have been prosecuted for offences against at least three victims while he was alive, two separate reports said today.
The allegations began with the ITV documentary Exposure. Here are some of the key points as the case unfolded.
A solicitor for the comedian Jim Davidson has said his client denies allegations against him following his arrest under Operation Yewtree.
Peter Watt, director of child protection advice and awareness at NSPCC said Savile is one of the most prolific sex offenders the organisation has dealt with in its 129-year history. He said:
It's clear Savile cunningly built his entire life into gaining access to vulnerable children. The sheer scale of Savile's abuse over six decades simply beggars belief.
One of Jimmy Savile's victims says the presenter laughed as a man hit a nine-year-old scout they had both abused. Speaking to BBC Radio Five Live, Kevin Cook said he was abused when he visited the BBC in West London for Jim'll Fix It.
I'm shocked by the amount and the time it's gone on and the amount that's gone on. I'm lost for words... The man walked into the room and carried on the abuse. He made me do stuff to him and he physically abused me as well, he hit me.
- 450 people have come forward alleging sexual abuse by Savile since October
- 328 of these people were children when they were preyed upon
- 214 criminal offences have been linked to Savile across 28 police forces
- 34 of these are allegations of rape
- 14 offences were committed at schools, in some cases after children wrote to Savile as part of Jim'll Fix It
- 57 allegations have been linked to hospital premises, including hospices
- 33 claims of abuse have been linked to television or radio studios
Peter Saunders from the National Association for People Abused in Childhood and Debbie Curtis, who Jimmy Savile tried to assault when she was just 22, told Nina Hossain how Savile's celebrity status allowed him to keep the "worst kind of open secret".
Further analysis of Jimmy Savile figures shows 66 of his victims were aged 13 or under, of those 28 were under 10 years old, including both boys and girls.
An alleged victim of Savile says she was told by police in 2008 that she risked being branded a 'liar', while his lawyers 'made mincemeat of her'.
Because he had plenty of money, Jimmy Savile would have the best lawyers, it would all take place in a big court in London and his lawyers would make mincemeat of her. She also got the clear impression from the police that she would be publicly branded a liar and that her name would be all over the newspapers, particularly if she lost the case.
An allegation also emerged today that Jimmy Savile sexually touched a girl aged between 13 and 16 at the final regular recording of 'Top Of The Pops' at Television Centre in 2006.
Speaking to our UK Editor Lucy Manning, Met Commander Peter Spindler said he hoped today's reports would help give victims a voice and sense of justice.
The BBC today said it was "appalled" that some of the offences by Jimmy Savile "were committed on its premises", adding that it "would like to restate our sincere apology to the victims of these crimes".

The Prime Minister's view of this is that it is absolutely right that every institution involved gets to the bottom of what has gone on.
