Jimmy Savile abused up to 214 victims between over 54 years, with the last offence being record in 2009, two years before he died.
The full scale of his abuse may never be known, but the numbers of victims in the NSPCC/Police report into his crimes are staggering.
Commander Peter Spindler of the Metropolitan police said Savile "groomed the nation" using his star status to "hide in plain sight."
"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.," he said.

Detective Superintendent David Gray, the police' leading investigator said Savile spent "every minute of every waking day thinking about it whenever an opportunity came along he has taken it. He is programmed to think and act in that way. He only picked the most vulnerable, the ones least likely to speak out against him."
Peter Watt, NSPCC Director of Child Protection Advice and Awareness, who co-authored the report, said that the scale of Savile's abuse "simply beggared belief."

"We know from the huge increase in calls to the NSPCC helpline about sexual abuse that the problem did not die with Savile," said Mr Watt.
"It's clear Savile cunningly built his entire life into gaining access to vulnerable children," he added.
