An investigation is underway after one of Ana Kriegel's killers was allegedly assaulted in Oberstown Detention Centre in Dublin over the weekend.
BOY A was handed a life sentence last November for murder and aggravated sexual assault, with a review to take place after twelve years.
It has been almost a year since BOY A was found guilty of murdering Ana Kriegel at a derelict farmhouse in Lucan, Co. Dublin in May 2018.
The then 13-year-old beat her to death after his co-accused, BOY B, lured her from her home in Leixlip, Co. Kildare.
BOY B was also found guilty of her murder but is in the process of appealing his conviction.
The boys, who can never be identified because of their ages at the time, are serving their sentences at Oberstown Detention Centre in north Co. Dublin.
Gardaí have this evening confirmed they are investigating an alleged assault on BOY A.
They’re looking into claims he was beaten up by other young offenders in a communal area at Oberstown on Sunday evening.
