A MAN who pleaded with doctors to treat his suicidal thoughts died hours later – by walking in front of a train, it has emerged.

James Whitelaw, 27, who had a history of depression, asked doctors at the Royal Alexandra Hospital, in Paisley, Scotland, to "put him to sleep" shortly before he took his own life.

His devastated sister Rachel, 25, said her brother was told he would have to wait for two hours to get psychiatric help at the hospital – but he left and killed himself.

She told the Paisley Daily Express: "James never got the help he needed and deserved.

"He would never have walked to the hospital if he wasn't absolutely desperate for help.

"They let him down, but they've also destroyed the rest of our lives.

"The guilt will live with all of us, it's always 'if only' and 'what if'".

An NHS inquiry into his death revealed there was a "gap in communication" regarding the severity of Mr Whitelaw's condition as he was assessed as "medium risk".

NHS Greater Glasgow and Clyde, which launched a major inquiry into his death, said improvements "must be made".

A spokeswoman said: "Sadly, we acknowledge this tragic incident which staff are devastated about.

"Following James' tragic death, we launched a significant clinical incident investigation and clinical and management staff met with his family to discuss its findings.

"The family was also given a copy of the report.

"Despite the patient being appropriately triaged, the review highlighted a gap in process regarding communication of supervision required following a change in category from medium to high risk.

"As a result of this dreadful incident, we have changed our communication processes regarding the level of supervision required for vulnerable individuals.

"We are also in the process of reviewing the layout of the department to make improvements which will help us care for patients with mental health issues.

"Our thoughts are with James' family as they continue to mourn his death."
