YEP Says: Where was duty of care at St James's Hospital in Leeds?

Where was the duty of care to Ken Goward and Roger Lamb on that hospital ward - and equally where was the duty of care to Harry Bosomworth, whose mental health needs should have been met to keep him safe and to protect fellow patients and staff on the ward.

Why was a patient who had been treated for paranoid schizophrenia since 1980 taken off his anti-psychotic drug - surely his medical background was known and failing that his family should have been listened to.

Mr Bosomworth had earlier been abusive to staff and security staff had had to be called. Why then was he left on the ward alone, where he later set about fellow patients with his walking stick.
