The cause of Simon Gelder's death still remains unknown despite an inquiry by Wakefield Council and an inquest.

Mr Gelder was found dead in bed with one of his clients at his luxury home.

Senior management at Wakefield Council had failed to take action against Simon Gelder despite staff at Warren Court in Wakefield reporting allegations that he was involved in drug abuse.

He was found on April 25, 2006. Present at the scene was a tenant of Warren Court, which cares for people with severe mental health problems.

Work colleagues made the discovery after bursting into his home in the Boothroyd apartments in Dewsbury.

Extracts of an investigation into Mr Gelder's death – obtained by the YEP under the Freedom of Information Act – reveal he had a relationship with a client that went "beyond professional codes of conduct".

The report also reveals deeper failures at Warren Court, including staff feeling isolated, undervalued and at risk while caring for patients.

Before Mr Gelder's death, question marks were raised over his ability to manage but his superiors took no action.

Independent investigator Stuart Green states: "In some instances a more formal admonishment would have been merited."

After Mr Gelder's death, a 37-year-old man was detained under the Mental Health Act and a 25-year-old man arrested on suspicion of supplying drugs.

The full facts surrounding Mr Gelder's death remain unclear after the date of his inquest was not made known. A request by the YEP for a transcript was refused by Bradford district coroner Roger Whittaker.
