Former detective constable Maggie Oliver has revealed how she wrote to 'my Rochdale girls' before entering the Celebrity Big Brother house as she is tipped to win this year's show.
Ms Oliver, who won the confidence of abused girls to persuade them to talk to police, said she had written to the victims because she didn't want them to feel let down by her.
She was one of the first housemates to join the Channel 5 reality show during its live opening on Tuesday night and has become an early favourite to win the show.
Maggie Oliver, who helped expose the Rochdale child sex abuse ring, was one of the first to enter the CBB house during the launch last night
As she headed into the CBB house last night Ms Oliver told host Emma Willis how the victims of the Rochdale sex scandal still held a special place in her heart.
She said: 'There's something I would like to say as it's a burning feeling in me that I really wanted to go and tell my Rochdale girls that I was coming on here, because the last thing I want is for them to feel let down by me.
'They are very close to my heart.'
She added: 'I have written all of them a letter, so girls, you'll be getting a letter tomorrow morning.'
Ms Oliver resigned after 16 years with the police following its handling of the sex abuse scandal in Rochdale
Ms Oliver was the police detective who persuaded young girls who were being sexually abused in Rochdale to speak to police.
The victims were white, working class and predominantly from broken or chaotic homes.
The scandal culminated in ringleader Shabir Ahmed ('Daddy') and eight accomplices, many of them taxi drivers, being jailed for a total of 77 years in 2012.
