A man accused of killing a father of four in his Rye home feared he was being controlled by aliens, a court has heard.

John Woodruff, 25, who has pleaded not guilty to murdering 72-year-old Barry Gray on the grounds of mental impairment, also believed the Greek God Zeus was inside him.

Supreme Court Justice Elizabeth Hollingworth told a jury they had to decide if Mr Woodruff was fit to stand trial on charges of murder, aggravated burglary, car theft and stealing petrol.

Justice Hollingworth said the Crown case against Mr Woodruff was that he had broken into Mr Gray's Parson Street home on May 7, 2013, and stabbed him to death before stealing his car.
