Violent stabbing accused "inspired by ISIS", say police

A RADICAL inspired by Islamic State allegedly stabbed his neighbour in an act of terrorism in a Sydney suburb, but the Prime Minister has said it is unlikely to change the nation's terror threat level.

News Corp is reporting Ihsas Khan, 22, was charged with committing a terrorist act and attempted murder after allegedly stabbing Wayne Greenhalgh, 59, as he walked his dog on Saturday afternoon.

Khan had a reputation of "odd" behaviours, which included yelling religious verses at neighbours, police said.

The Daily Telegraph reports Khan was trying to kill Mr Greenhalgh by striking his neck, chest and torso.

Mr Greenhalgh was able to drag himself into a nearby hairdressing salon, as Khan allegedly shouted at him in Arabic and banged his head against the glass doors.

He was later airlifted to Liverpool Hospital with serious injuries.

He has since undergone eight hours of emergency surgery.

New South Wales Police Deputy Commissioner Cath Burn said police will allege that Khan was "inspired by ISIS".

"It was a deliberate act yesterday, it resulted in a person receiving extremely serious injuries.

"We know that this person has strong extremist beliefs inspired by ISIS ... but what made him act yesterday we don't know.

"It was deliberate, it was violent, his behaviour could have turned worse as well."
