The Court of Appeal has found that the sentence of a teenager, who attempted to murder a woman he met on a dating app, was too lenient.
The Director of Public Prosecutions had argued that a review of the sentence imposed on the teenager after a five-year period was too early.
The now 17-year-old has been in custody since December 2017, when he lured Stephanie Ng to an isolated area at the Sea Front, Queen's Road, Dun Laoghaire.
After pleading guilty to a charge of attempted murder, he was sentenced to 11 years in detention in November 2019 with a review to commence on 1 January 2023.
The State appealed on the grounds of "unduly leniency".
The boy had met his 25-year-old victim on the Whisper social media app, where he had pretended to be 19.
He was 15-years-old when he tried to kill Ms Ng during their first face-to-face meeting, after suggesting they take a selfie by the water's edge.
There, he grabbed her from behind and choked her to unconsciousness before slashing her neck with a knife.
She attended a remote hearing of the Court of Appeal in May, where the Director of Public Prosecutions appealed the leniency of the sentence imposed on her attacker.
The boy and his parents also attended remotely from where he is detained at Oberstown Children Detention Campus.
Anne-Marie Lawlor SC told the court that the DPP was not taking issue with the sentence of 11 years, but said that the review after five years did not reflect the gravity of the offence.
The President of the Court of Appeal, Justice George Birmingham, presiding with Justice Patrick McCarthy and Justice Isobel Kennedy, delivered judgment today and invited both parties to liaise ahead of resentencing.
