Photographer Bob Carlos Clarke is reported to have suffered from clinical depression and was a voluntary patient at The Priory hospital in south-west London before he was hit by a train and died on 25 March.
The photographer was buried after a private ceremony held at the Brompton Cemetery in London, a place where he took many of his pictures.
Bob Carlos Clarke, 55, died at the White Hart Lane level-crossing near Barnes after apparently throwing himself in front of a Waterloo bound train, according to a witness at the scene.
It has been confirmed to AP that shortly before he died the photographer had said to a member of the hospital?s staff that he was going out and had signed out of the grounds in accordance with hospital procedures, according to a spokeswoman for The Priory who told us: ?Our clinical governance procedures and risk assessment procedures are superlative so there wasn?t any kind of systems failure.?
Risk assessment is agreed with both the patient and the patient?s family. ?Our patients are voluntary so they are free to use the grounds and to go out into the community as part of a therapeutic programme and re-entry to normal life,? she added.
The Priory spokeswoman insisted that correct procedures were followed but confirmed that it will conduct a ?review? in wake of the death.
Bob Carlos Clarke was being treated for ?severe clinical depression?, according to today?s Independent newspaper but the hospital ? based in Roehampton – refused to confirm this.
An inquest into the photographer?s death was last week opened and adjourned to a date yet to be fixed. Police are not treating his death as suspicious.
A memorial service will be held shortly, details of which have yet to be confirmed.
