A judge has told a convicted sex attacker, who raped a woman just days after he was released from prison, that he "may never be released".
Rory Griffin has been jailed for an indefinite period
Rory Griffin, 23, was under supervision at a bail hostel in Basildon, Essex, when he attacked the 50-year-old in May 2006, Chelmsford Crown Court heard.
Judge Peter Fenn jailed Griffin for an indefinite period for the protection of the public.
Griffin had pleaded guilty to two counts of rape at an earlier hearing.
Sentencing Griffin on Tuesday, Judge Fenn said: "It is quite clear to me that you are a man who is and will remain for some time a danger to women.
"The sentence I impose is one of an indefinite period for the public's protection."
Judge Fenn said Griffin would serve a minimum of 12 years before being considered for parole, but added: "You may never be released."
The court heard Griffin had served five years of a nine-year sentence for rape and indecent assault on an 18-year-old girl in April 2000.
Andrew Jackson, prosecuting, said that on his release in May 2006 Griffin was sent to Felmores Bail Hostel in Basildon where he was categorised as a high risk.
Mr Jackson said strict conditions were imposed on Griffin.
He was required to sign a register at the hostel every two hours between 0900 and 2100 BST and a curfew was in place between 2300 and 0930 BST.
Mr Jackson said in May Griffin had noticed a woman in a nearby park, who was described in court as vulnerable.
Left bail hostel
The married woman, the court heard, was depressed and had taken a bottle of vodka and orange juice to the park.
Mr Jackson said Griffin left the hostel at 2112 BST and approached the woman.
He said the pair went to a nearby pub and then returned to the park where Griffin raped the woman twice.
Griffin did not return to the bail hostel and was arrested in Chelmsford after he was seen by an off duty police officer.
David Holborn, defending, described the case as an "appalling situation" and said his client was suffering from a psychopathic disorder and was being examined at Rampton Hospital.
A National Probation Service spokeswoman said: "This is clearly an appalling offence. It is vital that we have the best possible systems in place to manage offenders effectively and the supervision of offenders forms an important part of our ongoing home office review."
