Police have warned Big Brother UK bosses over one of the housemates set to enter the show tonight.
BBUK kicked off its fourteenth series last night, as the first nine Big Brother 2013 housemates were revealed.
But it was just the first half of this year's live launch, which continues tonight on Channel 5 with another six housemates set to enter.
One of those taking part is a former police officer, said to have recently been working on Operation Yewtree, which has been been investigating the Jimmy Savile sexual abuse scandal since last autumn.
An insider claimed to the Daily Star: “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.”
However a spokesperson for Scotland Yard commented yesterday: "We are aware of reports concerning the proposed media appearance of a former detective constable.
"We have been in contact with Channel 5 and made them fully aware of potential risks and their responsibility to live investigations.
"All officers joining the MPS (Metropolitan Police Service) and leaving the MPS are required to sign the Official Secrets Act."
A spokesperson for Channel 5 reacted: "Channel 5 takes its obligations as a broadcaster seriously and, as has been made clear to New Scotland Yard, extensive procedures are in place to ensure that nothing will be broadcast during the course of Big Brother which would involve the former police officer breaching confidentiality, invading the privacy of others, committing libel or a contempt of court."
Big Brother 2013 continues tonight live on Channel 5 from 9PM.
