Four NSW police officers have been charged after allegedly lying under oath about the shooting of a mentally-ill man.
The charges come five years after Adam Salter, 36, died from a police gunshot wound in the kitchen of his father's Lakemba home following an attempt to stab himself in the neck.
The Police Integrity Commission (PIC) last year handed down scathing findings about how police handled the case, including the actions of senior officers.
After its inquiry, PIC recommended Constable Aaron Abela, Sergeant Sheree Bissett, Sergeant Emily Metcalfe and Senior Constable Leah Wilson face charges for allegedly lying to the watchdog.
The officers claimed Mr Salter grappled with Const Abela before Sgt Bissett shot him in the back.
But paramedics and Mr Salter's father said there was no contact.
Wilson, Abela and Metcalfe have been charged with perjury and giving false evidence, and have already faced a Sydney court, AAP has learned.
Bissett has been charged with one count of giving false evidence to the commission and also fronted Downing Centre Local Court last Thursday.
The PIC was also critical of veteran Detective Inspector Russell Oxford's leadership of a critical incident investigation into the fatal shooting. It recommended he face disciplinary action for misconduct.
The commission made the same recommendation for Inspector Matthew Hanlon, who prepared a report on the case, and Detective Inspector Stephen Tedder, who conducted an investigative review.
The commission criticised Det Insp Oxford's handling of witness accounts and the evidence considered in a number of his findings.
However, the NSW Police Force conducted its own investigation and found PIC's findings relating to him, Insp Tedder and Insp Hanlon weren't sustained, according to a PIC report released this week.
The officers were counselled.
Det Insp Oxford is an experienced officer who has worked on high-profile investigations, including the murder of six-year-old Kiesha Abrahams and more recently, the arrest of former detective Roger Rogerson.
Comment has been sought from NSW Police.
The cases of the four charged officers have been adjourned to Downing Centre Local Court in December.
