A Derby man accused of beating his partner and leaving her to die in a bath suffers from hallucinations and hears voices, a court has heard. Atual Mustafa's defence called three consultant psychiatrists who all said he showed signs of paranoid schizophrenia. Derby Crown Court heard his symptoms included laughing, delusions and believing there was a plot against him. He had previously been diagnosed with the condition, the jury heard. The court had been told earlier that Mr Mustafa, who denies murder, subjected Sobhia Khan to beatings as soon as she moved into his Normanton home in April 2017. Trial continues.
