Robert Quigley subjected a previous victim to a six-hour physical and sexual attack in the Dublin mountains last year. The attack only ended when he was disturbed by hillwalkers.
The victim on that occasion, a 22-year-old woman, mistook his car for a hackney cab which she hailed after leaving a nightclub on Harcourt Street in Dublin city in November 2006. She had been out with family and friends celebrating her graduation from a master's university course.
While sitting in his car she fell asleep for a period, awaking to find he had driven her to the Dublin Mountains.
Quigley told her he was a garda and claimed he had found drugs in her bag and was arresting her. He tied her hands behind her back using plastic cable ties. He beat her across the head with a baton and tried to strangle her. He told her that he had once come close to killing somebody. He then sexually assaulted her. His victim later told his trial she feared she was about to be raped.
Her ordeal ended when she managed to get out of his car where he had parked it on Military Road, Glencree, Co Dublin, as daylight broke. Quigley saw a group of hill walkers in the area and was forced to speed away in his car rather than go after his victim. The ordeal lasted almost six hours.
Quigley was caught when a garda working in Tralee, Co Kerry, recognised a description of his vehicle.
Judge Carroll Moran last August sentenced Quigley to 12 years for false imprisonment, assault and sexual assault.
