The mother of a man found hanging in a prison cell told staff he had threatened to kill himself a few hours before his death, a report has found.
David O'Driscoll, 30, died on August 12th, 2016 at Maghaberry Prison in Antrim after he was found in a cell in the jail's committal house seven hours after arriving at the unit.
A few hours before his death, Mr O'Driscoll's mother had phoned the prison to raise concerns about her son's welfare after he had called her home and threatened to kill himself, the Interim Prisoner Ombudsman's report said.
After making inquiries, the day manager on duty returned Mrs O'Driscoll's telephone call and reassured her that her son was fine.
Mr O'Driscoll died later that evening.
The investigation identified that no one had spoken directly to Mr O'Driscoll about the call he had made to his mother's home, and the reassurance given to Mrs O'Driscoll was based on earlier interactions an officer on the committal landing had with him.
Interim Prisoner Ombudsman for Northern Ireland, Brendan McGuigan, said: "It is particularly distressing in this case that after being reassured by the prison about her son's wellbeing, Mrs O'Driscoll was later told that he had died.
"This case highlights important lessons about how information provided from relatives of those in prison should be addressed.
"I wish to impress on prison staff the importance of staff handovers and record keeping which in this case fell short of the standards required.
"The investigation identified an inadequate handover from NIPS (Northern Ireland Prison Service) day staff to night staff and poor record keeping, which regrettably is a recurrent finding in Prisoner Ombudsman death in custody investigations."
A clinical review conducted as part of the investigation raised potential concerns around the continuity of Mr O'Driscoll's access to medication from his time in custody.
Following his arrival in prison, a committal nurse identified that he required medication and made arrangements for this to be prescribed.
The prescription was dealt with by an out-of-hours GP service and two medications were prescribed, but at the time of his death Mr O'Driscoll's medication had not been administered.
A separate clinical review of the resuscitation attempt concluded that it was commenced promptly and carried out in as effective and efficient a manner as possible after Mr O'Driscoll was found.
The report makes 11 recommendations for improvement, the majority of which have been accepted by NIPS and South Eastern Health and Social Care Trust (SEHSCT).
The head of the Northern Ireland Prison Service, Ronnie Armour, said: "I want to extend my sympathies to David's family. I very much appreciate how difficult the findings of this report will be for them, and on behalf of the Prison Service I want to apologise for the fact that David died in our care.
"It is important to recognise the difficult and challenging circumstances that prison staff encounter every day. In the last year alone, prison officers at Maghaberry Prison have saved 12 lives.
