Accused Sydney fruit shop murderer Linh Dang will remain behind bars as the hunt continues for his alleged accomplice.
Police allege 27-year-old Dang was armed with a silver-coloured pistol when he walked into the Villawood Value Fruit Market with another unknown man on Saturday afternoon.
But what began as a robbery quickly turned deadly when a 28-year-old employee put up a fight, Fairfield Local Area Commander Peter Lennon says.
"This (employee) has tried to struggle with these people, unfortunately he's died as a result of his injuries," Superintendent Lennon told reporters on Sunday.
The victim, named in court papers as Kamran Yousaf, was lying at the back of the shop with fatal bullet wounds to the head and abdomen when police and paramedics arrived.
He couldn't be revived.
Dang was arrested at the scene and charged with murder and armed robbery in company, and did not apply for bail when he fronted Parramatta Bail Court on Sunday.
Bail was formally refused and he will remain in custody while he awaits his next court appearance on December 12.
Court papers indicate he is accused of stealing an unknown amount of cash.
Supt Lennon said the Sadleir man had been questioned but refused to identify his alleged accomplice, who ran out of the fruit shop onto Woodville Road after the shooting about 3.40pm (AEDT) on Saturday and was still on the run on Sunday.
Little is known about the suspected shooter and detectives are scouring CCTV footage and interviewing the dozens of potential witnesses at the busy mall on Saturday.
"I haven't got that much of a description of him at this stage, other than he is a male person," Supt Lennon said, adding the suspect could be armed.
"There may even be people that know this man.
"You don't carry this sort of detail and guilt without talking to other people, or other people noticing a change."
He said the incident should serve as a warning to the public not to put their lives on the line to try to thwart would-be robbers.
"Don't confront these sorts of people," he said.
"I don't know what was going through (this victim's) mind, no one's going to know what was going through his mind.
"The price you pay is not worth it."
The man known as Mr Yousaf is yet to be formally identified and no loved ones have come forward, with police now turning their attention abroad as they try to track down the man's family.
It's not the first time a robbery or attempted robbery has occurred at the southwest Sydney shopping centre.
A nearby newsagent and the post office have been targeted in the past three weeks.
Detectives will investigate whether the shooting may be linked to the earlier incidents.Meanwhile, two police officers and a motorist injured in a car crash as the officers raced to the scene of the shooting have all been released from hospital.
