On 15th August 2022, Daniel Harrison appeared before HHJ Paul Thomas QC at Swansea Crown Court, where he pleaded guilty to manslaughter due to Diminished Responsibility. William Hughes QC, leading Carina Hughes of CPS Swansea, appeared on behalf of the Prosecution.

In this tragic case, the defendant was found to be suffering from paranoid schizophrenia  at the time he killed his father. On the day of the attack on his father, the defendant escaped from the mental health ward at Neath & Port Talbot Hospital and attended his parents' home in Clydach, Swansea. His father allowed him access to the premises and was immediately attacked by his son. The fatal injuries received led to Dr Harrison's death one month later. After hearing the psychiatric evidence, HHJ Thomas QC sentenced the Defendant to a s37 Mental Health Act 1983 Hospital Order, with restriction pursuant to s41 Mental Health Act
