Mr Brooke said CCTV footage showed Mr Riley visiting Wilson’s home on June 26 and leaving before Wilson came out and the two were later seen arguing, accordng to witness reports.

Shortly afterwards, a resident on Darley Avenue, Athersley, called the police, according to Mr Brooke, and said a man had come into her garden and was banging on her window saying, “help me, I have been stabbed”.

Mr Brooke said: “The police and paramedics came and found the victim Stephen Riley, aged 43, slumped over a small garden wall at the front of her property.”

Judge Roger Thomas QC told Wilson: “In my judgement, there can be no doubt at all that you were the one who purposefully armed yourself with a knife when you set off from your house in pursuit of Stephen Riley and hunted him down in the garden where he was trying to hide.

"You then quickly entered that garden and in the 15 seconds or so that you were there you used that knife and struck him those two susbtantial blows with it.”

The defendant, who had been seen out on a bicycle on the evening of June 26, had initially claimed he and his partner had been drinking heavily on June 25 and he had not left home on June 26 and he later claimed he had acted in self-defence with the suggestion Mr Riley had possessed the knife.
