An allegedly ISIS-inspired attack on a man in a southwestern Sydney neighbourhood has left residents fearing for their safety.

Vision from seven nearby security cameras aired on A Current Affair shows Wayne Greenhalgh, 59, being carried on a stretcher through a blood-soaked Minto hair salon run out of the home of Andrew and Dwen Horton.

Mr Greenhalgh walked past the salon as he often did on his Saturday afternoon strolls. But seconds later, he can be seen running for his life and begging Mrs Horton to lock the salon doors behind him.

His throat was cut, his arms were slashed multiple times and his fingers were severed.

"There was so much blood, all I could see was his fingers. On his right hand, I could see the bones," Mr Horton told A Current Affair .

"It's come into our privacy, it's landed right on top of where we live."

Women were seated inside the salon, among them was Meribell Brooks.

"He kept saying to me, he sort of lifted his fingers and his arms and was looking at them, and he said 'look what he did to me, why? why?'" Mrs Brooks said.

"He wouldn't sit down and he kept telling me, 'I'm alright love, I'm alright.'"

Caught on another security camera are the efforts of Sivei Ah Chong, who has been hailed a hero for his role in mitigating the alleged terror attack.

Mr Ah Chong and his family stayed on the attacker until police arrived.

"He just stood there and he was trying to attack me," Mr Ah Chong said.

"I said, 'mate, you do that to me, I'll kill you. You know, I'll kill you.' He said, 'oh, do that, I'm here to die, I'm ready to die.'"

Mr Ah Chong bashed the alleged terrorist over the head with a fence paling he snapped in half.

It did nothing except make him more agitated.

"He just said the same thing," Mr Ah Chong said.

"'These people are killing my brothers and sisters in Iraq.'"

Outside the salon, Ray Brooks watched police bring down the man at the end of his driveway.

He had no idea his wife was inside getting hear hair done at the time of the attack.

"He was holding a very large knife and threatening a male and female constable," Mr Brooks said.

"The male constable had his taser drawn, the female officer was covering him with her pistol drawn."

"They were trying to get him on the ground and to drop the weapon, so they could end it peacefully."

The neighbours of the man police charged over the attack had reported he had shown “strange behaviour” in recent weeks, including running on to the road and stopping traffic.

It is understood police will attempt to build a profile of him in the coming days.
