A man jailed for the rape and sexual assault of a woman whose child he abducted in the same incident has had his sentence increased to 19 years following an appeal by the Director of Public Prosecutions.

Michael Murray, formerly of Killiney Oaks, Killiney, Dublin, had previously been sentenced to 15 years.

The 46-year-old was convicted for rape, attempted rape, oral rape and aggravated sexual assault, child abduction, threats to kill or cause serious harm, false imprisonment and theft at a Dublin apartment on 12 and 13 February 2010.

The Central Criminal Court heard that Murray had lured his female victim into an apartment by telling her that an elderly woman was dying inside and needed her help.

He tied her up and assaulted her before taking her four-year-old son away, abandoning him in a city centre square late at night.

He returned to the flat where he drugged and raped his victim.

Murray had denied the charges. However, he was found guilty on all counts by a unanimous jury verdict.

The DPP successfully sought a review of Murray's 15-year prison sentence on grounds that it was "unduly lenient".

The three-judge Court of Appeal acceded to the DPP's appeal and re-sentenced Murray to 19 years in prison.

Noeline Blackwell, CEO of Dublin Rape Crisis centre, said of the sentence: "The desperate harm that he did and the extent of the brutality of the rape and also involving the child in it, means it had to be treated as serious as it could get and that's what the court of appeal found today.

"They found it at the upper limit of the most serious crime. It is as long a sentence as the court of appeal has handed down in a long time."
