The Court of Appeal has tripled the jail sentence of a Dublin man (74) in ill-health who repeatedly raped his daughter when she was a child.

Patrick O'Brien of Mackintosh Park, Pottery Road in Dun Laoighaire will now serve nine years in prison after pleading guilty to the abuse of Fiona Doyle between 1973 to 1982.

In 2013, O'Brien was given a 12 year sentence for what was described as one of the worst cases of sexual abuse one could possibly find.

However because of his age and ill-health, nine years of his sentence were suspended and he was granted bail pending an appeal - a move which sparked uproar.

Last month the Court of Appeal ruled the suspended portion of the sentence was too lenient despite his ill-health - which can be accommodated behind bars.

Today the court, presided over by its President Sean Ryan, imposed a new sentence of 12 years with three years suspended - essentially tripling the jail time of O'Brien.

However the judge did note that if his health further declines, the executive has the power to grant remission.

This afternoon, Fiona Doyle spoke to Lunchtime with Jonathan Healy and said that she was delighted the message this sent out for other victims of abuse.

"I won't stop now. I will fight on that these changes will be made."

On whether she would raise these issues with the Justice Minister and the Taoiseach, Fiona stated: "I want these issues to be brought to their attention. I've asked for the book of evidence."

Jonathan asked did the case bring her closure to which she replied: "I'm not a victim anymore, I'm a survivor."

Doyle spoke at a press conference today, telling the press: "To many victims out there have not had their vocies," before introducing Ellen O’Malley-Dunlop, Director of the Dublin Rape Crisis Centre, to put Fiona’s story into the larger context of the problem of sexual violence in Ireland.
