Westfield Bondi Junction: Female police officer's 'incredible act' after shooting Sydney mall killer

The police officer who shot a man responsible for stabbing people inside a Sydney mall has been applauded for her acts of bravery and heroism.

Six people were killed, and several others wounded, in the attack by a 40-year-old man at Westfield Bondi Junction shopping centre on Saturday. 

One of the victims includes the mother of an injured nine-month-old baby. 

NSW Police Inspector Amy Scott was reportedly the first officer inside the mall, and took on the armed attacker, before shooting him in the chest when he lunged at her. 

Scott then performed CPR on the killer, along with victims lying on the ground as she waited for back-up to arrive. 

"She was there on her own and she went towards the danger," Waverley Mayor Paula Masselos told Sky News UK. 

"Even [after she shot the attacker], she immediately began applying CPR - that just shows you the dedication of the person and her incredible act of heroism - even then her main concern was for someone who had fallen." 

Nearby cafe owner Michael Dunkley spoke with news.com.au after witnessing Scott shoot the attacker inside the mall. 

Dunkley said she asked him to "drop the knife" before the stabber lunged at her with a 15cm-long knife. 

"She was put in a situation where she had to do it. She did it so calmly. She was amazing," he said. 

NSW Police Commissioner Karen Webb said Inspector Scott was "doing well under the circumstances" on Saturday evening. 

"She showed enormous courage and bravery."

"She will be interviewed tomorrow." 

Webb said early indications suggest the attack was not related to terrorism. 

The attack unfolded inside the shopping mall after 3pm on Saturday (local time), where the man, wearing an NRL jersey, began stabbing shoppers. 

Five women and one man have been killed, and eight others remain in hospital with injuries. 

The shopping centre is closed today and remains a crime scene.
