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.
Former pop star Gary Glitter has been rebailed until early June after his arrest over alleged sex offences.
The 69-year-old was first held at his home in central London in October 2012 by officers from Operation Yewtree, the national investigation launched in the wake of abuse claims against Jimmy Savile.
Today Scotland Yard did not name Glitter, but said that a man in his 60s known as Yewtree 1 had been rebailed until early June.
The allegations against Glitter, real name Paul Gadd, are linked to late television presenter Savile. He was the first person to be arrested as part of Operation Yewtree.
A 78-year-old man has been charged with rape and indecent assault in connection with incidents at several hospitals including Stoke Mandeville in the 1970s and 1980s.
Michael Salmon, from Wood Green in Hampshire, was arrested as part of the Metropolitan Police Service's Operation Yewtree which was set up following the Jimmy Savile allegations.
He was arrested today and later charged with one count of rape and four counts of indecent assault by Thames Valley Police.
The charges relate to incidents involving four victims between 1972 to 1985 at hospitals in the Aylesbury area.
Salmon will appear at Aylesbury Magistrates' Court on December 17.
Paul Gambaccini has confirmed he was arrested as part of the Metropolitan Police's Operation Yewtree investigation and has denied all allegations, a spokesman for the BBC broadcaster said tonight.
Paul Gambaccini was released on bail after being arrested on suspicion of sexual offences by officers investigating Operation Yewtree.
A police spokesman refused to confirm the identity of the arrested man, but said:
The man was arrested at an address in south London on suspicion of sexual offences and taken into police custody.
He falls under the strand of the investigation we have termed 'others'.
Police confirmed that another man, aged 74, was also arrested as part of the investigation. Oficers said both have been bailed to a date in early January pending further inquiries
Paul Gambaccini decided he did not want to present his radio show tomorrow, and in his absence, the BBC said they would change their programming schedules. In a statement, a BBC spokesperson said:
Paul Gambaccini has decided that, in light of today's media attention, he would rather not be on-air at present and we respect that decision.
Therefore, Paul will not be presenting on BBC Radio in coming weeks and replacement programmes for the period will be announced soon.
Paul Gambaccini will not host his BBC Radio 2 show tomorrow evening, following his arrest on suspicion of sexual offences by officers investigating Operation Yewtree, the BBC said.

Veteran BBC TV and radio presenter Paul Gambaccini has been arrested on suspicion of sexual offences as part of the inquiry into alleged sexual offences by Jimmy Savile and others.
He was arrested on Tuesday under the "others" strand of the Operation Yewtree, meaning the allegations are not linked directly to Jimmy Savile.
Scotland Yard said on Tuesday that two men - aged 64 and 74 - were arrested at separate addresses in south London and taken into custody.
The two arrests on Tuesday are the 15th and 16th arrested as part of police inquiries.
Chris Denning is the 13th person to have been arrested under Operation Yewtree - the investigation sparked by the Jimmy Savile scandal.
The investigation is being run in three strands and the allegations against Denning fall into the category that does not involve Savile.
Mr Denning was part of the original DJ line-up when the BBC launched Radio One in 1967. He had previously worked as a BBC2 announcer.
A 72-year-old man, understood to be former Radio One DJ Chris Denning, has been arrested over further allegations of sexual offences by detectives from Operation Yewtree, Scotland Yard has said.
He was originally arrested on 3 June on suspicion of sexual offences and later released on bail.
Whilst Operation Yewtree was sparked by the Jimmy Savile abuse scandal, the claims against Mr Denning are not linked to the disgraced television presenter.
