Jimmy Savile's former chauffeur and flatmate Ray Teret has been released on bail after being arrested on suspicion of rape.
Teret, 71, was arrested in Altrincham following a police investigation into allegations of historic sexual abuse.
The accusations are not linked with the national inquiry into abuse by Savile, police said.
A 61-year-old man arrested at the same Woodlands Road address on suspicion of rape has also been bailed by police.
Detective Inspector Simon Davies, of Greater Manchester Police, said: "I want to make it absolutely clear that this is not an investigation into the late Jimmy Savile, nor do any of the allegations relate to any involvement by Savile."
He added: "The arrest follows an investigation by the Serious Sexual Offences Unit into three separate allegations of historic sexual abuse which have been reported to Greater Manchester Police since 28 October 2012."
According to Sky sources, the victims say the alleged offences took place around the time Teret was living with the disgraced television presenter in the Sale area.
They add Savile was not there when the alleged sexual abuse occurred.
The arrests came a day after Savile's nephew Guy Marsden backed calls for the body of the Top Of The Pops host to be exhumed and cremated .
