THE death of a man found hanging in a Hampshire prison was contributed to by neglect, a jury has found.

Daryl Hargrave from London, was found by staff in his cell at HMP Winchester six days after his arrival, Winchester Coroner's Court heard.

Over the course of the four-week-long inquest, jurors heard the circumstances surrounding the 22-year-old's death.

The jury read a narrative verdict to assistant coroner Karen Harrold following their deliberations.

The jury found that there was a failure by healthcare to provide treatment for psychosis, and that treatment could have been initiated on July 17, two days before Mr Hargrave's death.

The jurors also found that the decision not to put Mr Hargrave on constant supervision contributed to his death.

Ms Harrold said she intended to send preventing future deaths reports to various organisations.

"I remain gravely concerned that further action is needed," she said.

She added that her report would address a number of concerns including documentation of self-harm incidents, ensuring an adequate number of safer cells, and the quality of the ACCT documentation process.

She recorded that Mr Hargrave died as a result of suicide while suffering from psychosis and contributed to by neglect.

Following the conclusion, Nicola Hargrave, Mr Hargrave's mum, said: "We Daryl's family, feel the prison failed to act to prevent his death. We feel, and fear, there will be more without intervention, training and more resources. Daryl was loved and treasured by all who knew him."

The court had heard that Mr Hargrave had a history of self-harm and suicide attempts, and had suffered from mental health problems from a young age.

He was living in a hostel on St Vincent Road, Gosport, at the time he was remanded into custody on July 13 2015.

He was on the remand wing of the prison where he was being detained on a GBH charge.

Mr Hargrave was one of five men to die at the prison over a four-month period that year.

His death on July 19 at Royal Hampshire County Hospital came after that of Haydn Burton, whose inquest concluded in September 2016.

Nicola Hargrave, Mr Hargrave's mother, had told the inquest that in the past he had been ordering Diazepam, or Valium, off the internet to self-medicate.

"He was a very bright child, really interested in science and maths. His brain would work a hundred miles an hour," she said.

"Daryl felt he was in control, but he was all or nothing with his addictions."

Teresa Pedley, who Mr Hargrave lived with for a time in Gosport before his arrest, said: "My main objective was to keep him safe.

" I didn't like that he kept drinking while he was on anti-depressants, or taking St Johns Wort which I didn't think was safe."

"I was devastated and shocked by the news."

Pathologist Dr Basil Purdue told the jury that Mr Hargrave had a small amount of antidepressants and painkillers in his blood at therapeutic levels.

In prison, Mr Hargrave was placed on an ACCT, which allows staff to monitor prisoners in distress or at risk of suicide and self-harm.

He was also under twice daily observations as part of a detoxification plan to monitor his withdrawal symptoms.
