The new series of the reality show begins on Channel 5 on Thursday night, and according to the Daily Star a Yewtree cop is among the housemates.
The paper states that the high-ranking detective was "at the heart" of the investigation into allegations made against Savile and other famous names, but has recently quit the 30-strong force after feeling "upset" and "drained".
A TV insider told the paper: “The housemate knows they are going to hit the headlines over this. Leaving the police force to go into the Big Brother house is a massive move.
“Their former bosses are going to be shocked about their decision to join the show and naturally will be worried about what might be said inside the house. This person has seen a lot of bad things while working on Operation Yewtree.
“They will know what can and can’t be said inside the house but it’s only natural for their housemates to want to try to get as much gossip as possible.”
It isn't the first time the show has had a brush with Yewtree, as Jim Davidson was arrested in connection with the investigation, just days before he was due to enter the 'Celebrity Big Brother' house in January.
Meanwhile, it has also been rumoured that a former friend of recently scandal-hit Tulisa Contostavlos will also enter the house.
The Daily Star claimed that the music producer-turned-professional sportsman intends to reveal all about Tulisa’s "wild sex and drugs past", having grown up together on the streets of North London.
The former 'X Factor' judge was recently arrested on suspicion of supplying class A drugs, after an undercover reported working for The Sun alleged to have filmed her fixing up an £800 cocaine deal.
Other contestants rumoured to be entering the 'Big Brother' house include a Harry Styles look-a-like, a professional middleweight boxer, a lesbian fisherwoman and a gypsy gangster grandad.
'Big Brother: Secrets And Lies' launches tonight on Channel 5 at 9pm.
