He was jailed last year after he was found guilty of sexually assaulting several women and girls, but even more alleged victims have come forward with claims against the shame entertainer.
The 85-year-old was jailed in July 2014 after being found guilty of 12 counts of indecent assault against women and girls.
Eight more reported victims have now come forward with details of alleged attacks.
A legal source told the Mirror: “As I understand it there are about eight further charges in relation to other people.
“It’s similar to Jimmy Savile. They don’t know each other. They have given evidence not knowing what the other people are going to say and the evidence is strikingly similar.”
Harris is currently serving five years and nine months for the horrific attacks (some of his victims were as young as 8-years-old).
If found guilty of any further crimes then it is highly likely that Harris will spend the rest of his life in jail.
Harris was jailed as part of the Operation Yewtree, which is investigating historical sex offences made by some of the UK’s most high profile figures.
In an upcoming documentary, Harris’ crimes have been described as ‘extremely intimidatory’.
Solicitor Liz Dux, who was interviewed about his crimes, told the CI Channel: “He has displayed in his post-trial behaviour the exact traits that helped him get away worth it for so long.
“He’s saying. ‘I’m famous and you’re low life.’ That’s clearly why no one has spoken out about him before.”
The investigation into the latest accusations is still ongoing.
Crimes That Shook Britain starts with the Rolf Harris case this Sunday at 9pm on the CI channel.
