Jimmy Savile's former flatmate and chauffeur Ray Teret has been arrested in Cheshire, Greater Manchester Police have confirmed.
Detective Inspector Simon Davies said the arrest was nothing to do with the investigation into Jimmy Savile.
"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.
"A 71-year-old man was arrested on suspicion of rape following a warrant at an address on Woodlands Road, Altrincham.
"A 61-year-old man was also arrested at the same address on suspicion of rape in connection with one of the complaints.
"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.
"The victims who have come forward have shown tremendous courage and our primary focus is to support these victims during what is clearly a very traumatic time for them. We have a duty to investigate their complaints thoroughly.
Greater Manchester Police takes all reports of sexual abuse very seriously and we will look into any complaints and provide whatever support victims may need through the use of specially-trained officers.
"Anyone who is affected by this investigation can call police on 101 or the independent charity Crimestoppers, anonymously, on 0800 555 111."
