Philip Murphy (41) was formally disciplined by jail bosses in the Midlands Prison on Monday and the Prison Service have notified gardai who are expected to launch an investigation into the disturbing complaint.
“The governor of the prison received a complaint last week about these phone messages and a full investigation was launched in which all the calls that Murphy made on the prison phones were analysed last weekend,” a jail insider said.
“These calls are all recorded and evidence that he made very threatening and abusive calls was quickly discovered and this led Murphy being issued with a ‘P19’ disciplinary form on Monday which means that many of his privileges have been revoked.
“Gardai have been notified of these abusive phone calls.
“The nature of the messages he left for that woman were extreme in terms of the language that was used and the threats that were issued” the insider explained.
It can be revealed that during the Christmas period, Murphy left around seven highly disturbing voice messages on the phone of a woman who is known to him and who is understood to be traumatised by what has happened.
Apart from issuing death threats, Murphy also made a number of other vile threats such as threatening to cut the woman’s head off, slit her throat and dig up her grave, it has been alleged.
This is Murphy’s first serious disciplinary breach in jail since he was extradited from the UK almost two years ago.
He had been working as a cleaner in the prison and “generally keeping his head down until this happened” according to sources.
When contacted a spokesman for the Irish Prison Service said that they do not comment on individual prisoners.
Murphy is serving a six year jail sentence for random sex attacks on two women in Dublin city centre just two days after being released from custody for the false imprisonment offence of a woman and producing a knife during the a distrubing incident in 2008.
Last April, Dublin Circuit Court heard that Murphy had just been released from serving that 10-year prison sentence when he sexually assaulted the two women in February 2016 in the space of just 20 minutes.
During both incidents, Murphy grabbed the women from behind as they were walking on their own through the city in the early hours of the morning, told them he wanted to have sex with them and said he was going to kill them.
“You're going to die tonight,” he repeatedly told one victim.
It is understood that the Director of Public Prosecutions (DPP) will appeal the leniency of this sentence a court sitting in March.
The DPP is also expected to make a decision in the coming months on fresh charges against Murphy in relation to a major garda investigation into horrific historical sexual abuse allegations against him.
Last July, Murphy was arrested by Clondalkin gardai in the Midlands Prison who are investigating serious sexual offences against two juvenile females and a boy in west Dublin which are alleged to have happened over 20 years ago.
One of Murphy’s closest associates was also arrested last July as part of the same investigation.
Murphy has ten previous convictions, including one for carrying a Stanley knife and a number of public order offences.
Last year Murphy, of no fixed abode in the Dublin 8 area but originally from Clondalkin, pleaded guilty to two counts of sexually assaulting the two women at Jervis Lane and O'Rahilly Parade in Dublin city centre on February 25, 2016.
Passing sentence, Judge Melanie Greally said there was “every reason to conclude” that Murphy intended to engage in “very serious acts of sexual violence” but for the bravery and actions of the victims.
Judge Greally said the offending was aggravated by the fact he had recently been released from prison for the false imprisonment of a female. She said Murphy has a difficulty with alcohol and substance abuse which contributes to his offending behaviour.
She said the culpability in this case is “considerable” and the harm caused to the victims is “very substantial indeed”.
Judge Greally sentenced Murphy to six years imprisonment. She also ordered that he must undergo four years of post release supervision by the Probation Service during which time he must comply with all lawful directions of his Probation Officer.
In relation to his 2008 attack on the Polish woman in Clondalkin, Dublin Circuit Criminal Court was told Murphy was nominated as a suspect on the basis of his modus operandi.
Judge Frank O’Donnell said that during the trial it had been put to Murphy, who denied the charges, that he had been “scouring the countryside looking for a victim”, but noted that he could only deal with the evidence before him.
