Forty-year-old Jamaican Chan Wright was ordered by judge Lord Kinclaven to serve at least six years and it was recommended that he be deported.
An earlier attempt was made to deport Wright, who has a previous conviction for rape, but in 2007 three judges ruled that it would be “irrational and not justified” to do so.
As Wright was sentenced at the High Court in Glasgow yesterday, two of his victims, who cannot be named for legal reasons, hit out at the decision not to deport him earlier.
One of his victims, aged 33, said: “I feel let down by the system. Here was a man convicted of rape and threatened with deportation who appealed, and three Court of Session judges allowed him to remain in Scotland.
“A great many people would have been saved from a lot of misery had he been deported then. I was completely unaware that he had previously been convicted of rape.
“In 2005 he was challenging a deportation threat by immigration officials, but I was completely unaware of his background.
“The trial was a real ordeal, having to recount the trauma I had experienced plus discovering his physical and sexual assaults on other women.”
Another of his victims, aged 38, said: “I can look back now and see that a lot of pain could have been saved had he been deported.”
Wright was convicted last September of raping and assaulting three women and indecently assaulting two girls. The offences were committed in Edinburgh, West Lothian, Angus and Aberdeenshire over a 15-year period. The verdicts in these cases came four years after Court of Session judges stopped him being deported.
He continues to deny all the rapes and sexual assaults.
Wright, who has personality characteristics similar to a psychopath, raped and brutalised the three women over a 15-year period.
Experts say if he is ever released, he will need to be monitored round the clock by the authorities.
The Jamaican immigrant is unable to understand his victims’ pain and suffering.
Yesterday, Lord Kinclaven told Wright: “It is my opinion if at liberty you present a high risk to the public of violence and sexual violence. You are a risk to women.”
In September 2011 he was convicted of raping and brutalising three women. He also indecently assaulted another two women. The verdicts in these cases came four years after Court of Session judges stopped him being deported.
Then, an immigration tribunal decided the rapist and cocaine trafficker posed a high risk of committing further sex and drugs offences, but Lord Johnston, sitting with Lord Eassie and Lord Wheatley, said its conclusion was “irrational and not justified”.
Wright had already served four years for raping a teenager in Livingston in 1995.
A risk assessment report prepared by forensic psychologist Stephen Evan following Wright’s conviction concluded that he would pose a “high risk” of reoffending if released.
Mr Evans said that Wright was abused as a child. He added: “There are issues from his childhood which are clearly unresolved. Until these issues are resolved, Mr Wright is likely to continue to be a risk to women.”
