A man who shot dead a woman in the Irish Republic is in fear of his life after being viciously assaulted in prison for the second time.
Keith Hall (24) was set upon by a gang of inmates who poured boiling water on his face and body.
The brutal assault left the Tallaght man with serious burns and has led to fears that he will be subject to further attacks.
Sources today said he is back in custody but is under constant monitoring by the authorities at Mountjoy Prison.
Hall spent over a week in St James Hospital and was treated for burns to his throat, chest and back.
Sources say he was “pinned down” close to his cell last week by a number of inmates who were armed with a container filled with boiling water.
He screamed in agony and has been left with “serious burns”.
The incident has been referred to the gardai who have now launched a major probe.
It is the second time in just over a month that Hall has been attacked in prison.
In August, he was set upon by a gang of up to five inmates who slashed him in the face with a makeshift knife.
The incident took place just two days into his prison term for the manslaught of 16-year-old Melanie McCarthy McNamara.
He received over 50 stitches and is likely to have permanent scars to his face as a result of being slashed.
The family of murder victim Melanie McCarthy McNamara reacted with glee after Hall was sentenced to 20 years in prison on July 31.
Detective Superintendent Brian Sutton told the court that Melanie was sitting in a Nissan Primera with her boyfriend Christy Moran and his friend in Brookview on the nignht of February 7,2012.
A black Santa Fe jeep pulled up and a sawn-off shotgun was discharged into the rear passenger seat of the Primera, the court heard.
Melanie was shot in the head and was driven in the car to Tallaght Hospital but died of her injuries at 1.15am the next morning.
The court heard the Santa Fe had been stolen in Rathgar and had licence plates taken from the same type of vehicle. The shotgun had been stolen a year earlier in Kildare but its owner said it had not been sawn-off when it was taken. The jeep was later found at a bus terminus in City West.
Hall told gardai that Ms McCarthy-McNamara's boyfriend and another man were the intended victims of the attack. He said his role was to throw a rock at the window of the house to lure the occupants out of it and he helped dispose of the gun when the Santa Fe ran out of petrol at City West.
