A teenager told prison staff he had "seen the face of the Devil under his bed" in the run up to his death following a self-harm incident in a Scottish young offenders' institution, a court has heard.
Liam Kerr died in hospital in January 2017, less than a week after attempting suicide in , Stirlingshire.
The jail's former mental health nursing team leader told a into the incident she was aware that prison officers at the jail were "genuinely worried" about his mental health.
, 54, now a police nurse, said the mental health team had been requested to "review" Liam on January 6th, 2017, after the 19-year-old, from Paisley, Renfrewshire, set fire to his cell in the jail's - the segregation unit.
She confirmed that records made at the time read that Liam had "requested hot water to drink, and when he didn't get it, felt he was being treated as a daftie, so set fire to his cell".
The nursing notes continued: "Seen in cell in the company of Dunedin staff, Liam stated that he was unhappy with the way he was treated. Did acknowledge he should not have set fire, but said 'that's what happens when they make me angry'.
"[He] stated that he did hear voices, sometimes when he was angry. Stated they [the voices] told him whether people were bad or good.
"Also stated that he saw the face of the Devil under his bed and voices and a vision encouraging him to start the fire."
According to the notes, told nursing staff he did not hear the voices at all times, but did hear them daily. He told them his mental health was "OK" and he could "manage it" and refused to consider medication at that time.
Mrs Warner said she present the same day, January 6th, when Liam was seen by consultant psychiatrist Dr Rosa Serrano, of the Forth Valley Royal Hospital.
Mrs Warner said: "He seemed quite sensible to me. He engaged with us.
"He didn't present as psychotic. He restless, but he was aware, he was engaging. There was no evidence of psychosis at that point. He denied self harm, suicidal thoughts."
She said that Dr Serrano's plan was that she would see Liam the following week, and meanwhile the mental health team would monitor him.
The inquiry heard that Liam had been previously diagnosed as suffering from drug-induced psychosis.
In answer to questioning, Mrs Warner said such psychosis could re-occur, even when the sufferer was no longer taking the drugs that had brought it on.
The inquiry, at , heard that Liam, said to have "complex" mental health needs, had been in the prison for nearly eight weeks before the self-harm incident, when on the evening of January 13th, 2017, he made the attempt on his own life only hours after being seen by again by Dr Serrano, who ruled out an immediate transfer to a psychiatric ward.
Liam, who died in hospital six days later, was in the establishment on remand over allegations that he had robbed a sandwich shop in Paisley.
Earlier, warder Brian Ward, a prison officer at for 21 years, said officers in Dunedin hall had been "totally disheartened" by the feedback they got from mental health services over the teenager.
Referring to records Mr Ward, 48, told the inquiry: "He was shouting all the time, throwing food over his cell, saying there were other people in his cell with him when there weren't, screeching and shouting all night.
"He appeared to be speaking to his gran every day.
"He rubbed toothpaste over his body and head, and breaking into what appeared to be an Irish accent. His shouting was incoherent.
"It was 24 hours a day that was behaving that way.
"He was seen by a psychiatrist and a psychologist and the feedback we were given was that it was behavioural, not psychotic.
"We didn't agree with that.
"Myself and my colleagues were totally disheartened with the feedback we got for him. We were trying to deal with a person, care for them, and all our experience went for nothing."
The inquiry will continue in October.
