When the judge had passed sentence, the public gallery erupted into applause, and one woman shouted “Yes” and “monster”.
Mr Justice Baker said: “It is clear that you exploited your celebrity status to sexually abuse young girls when they were between 13 and 15 years of age.
“Those who were raped had little or no understanding what was happening to them and felt they could do little to prevent the abuse taking place.”
He said Teret’s “ill-judged cynicism” that his victims would not come forward was matched by his belief that the jury would not believe their accounts.
A jury had found the 73-year-old guilty of seven rapes and 11 indecent assaults which took place between 1963 and 1979. He was cleared of various sexual offences in relation to six other complainants.
Greater Manchester Police have confirmed they are investigating fresh sex allegations against Teret made by four other women since the trial began.
Detective Chief Inspector Graham Brock said: “After decades of hiding behind the veneer of being a distinguished radio presenter, Ray Teret has finally been exposed as the manipulative and dangerous sexual predator that he is.”
He said Teret “cast a dark shadow” over his victims’ lives, adding: “I know from speaking to them personally how devastating the effects of his abuse have been. They have courageously relived their ordeal at court and should be applauded for having the bravery to speak out and bring this man to justice for his appalling crimes.
During the trial prosecutor Tim Evans described many of the former DJ’s victims as “starstruck”, telling the jury: “The basic set-up, the background is the same – a naive girl who has the headlights of fame shone on her, who is taken to a flat and without more, without any understanding of what is going on, has a male many years older, having sex with her.”
