A YOUNG man stabbed his mum’s partner twice after a drunken quarrel, a court has heard.

The victim has recovered from his injuries but his attacker, Andrew McKeown, was jailed for seven years at Liverpool Crown Court today, Monday.

After ruling that 22-year-old McKeown is "dangerous" and "poses a significant risk of causing serious harm to others" Judge Robert Warnock imposed a two year extended licence.

The court heard that the incident happened in the early hours of October 19 last year during a disturbance outside McKeown's home in Leigh Road, Atherton.

A neighbour saw McKeown arguing with his mother's partner, Andrew Youds and then running at him and apparently punching him to the ribs.

But McKeown was actually armed with a kitchen knife and had stabbed him, said Paul Treble, prosecuting.

Mr Youds ran off but McKeown chased after him and following a conversation stabbed him again to the upper body.

The victim shouted that he had been stabbed and asked for an ambulance to be called.

He managed to walk away towards a bus stop where he collapsed and was attended to by McKeown's mother and a neighbour, who brought out a towel to staunch the bleeding.

"Meanwhile the defendant walked over to them and after a short conversion with his mother he pushed her causing her to fall over and then went to the complainant who was on the ground and seemed to kick him as hard as he could," said Mr Treble.

As he left the scene he warned, "If you grass me up I'll kill you."

When arrested and interviewed he admitted throwing the knife down a grid near his home and this was later recovered.

McKeown, whose previous convictions include assault and burglary, pleaded guilty to wounding with intent.

Martyn Walsh, defending, said that during the initial argument Mr Youds had thrown the first blow and invited McKeown to take the fight outside. They had always had a tempestuous relationship and had been drinking together that evening before the row took place.

"McKeown's temper goes badly with alcohol," he said.
