“A number of shots were fired” on Charles Street, Parramatta in western Sydney outside the New South Wales police headquarters about 4.30 pm (0630 GMT), police said in a statement.
Scipione said that police had no warning of the attack and that the 15-year-old, of Iraqi-Kurdish background and born in Iran, had not been on the police radar, nor had he any criminal history.
Mr Turnbull has spoken to Duncan Lewis, the director-general of security at the Australian Security Intelligence Organisation (ASIO) and Andrew Colvin, Commissioner of the Australian Federal Police about Friday’s shooting.
Australian Prime Minister Malcolm Turnbull described the shooting as a “shocking crime” at a news conference in Melbourne Saturday.
The suspect was killed when officers at the police headquarters returned fire.
THE gunman who shot dead a police staffer was a 15-year-old who had visited Parramatta Mosque on his way to commit murder.
Scipione praised officers for their response, saying: “In viewing video footage, I have witnessed enormous bravery by those special constables who responded”.
“We are not sure whether he was targeted because he came from a police facility”, Scipione said.
The victim was Curtis Cheng, a 17-year veteran of the police force’s finance department.
Reports suggest police had feared an attack for a few time.
Two people are believed to have been shot dead in Parramatta.
“The Muslim community are our absolutely necessary partners in combating this type of violent extremism”, he said, according to the AAP.
Police think he was acting alone, and do not know whether he’d been influenced or radicalized by someone else, Scipione said.
“When I went out there was two bodies on the floor and there was cops everywhere all around the area and they told me to go inside the shop straight away”, he said. “There’s no doubt that this tragedy will echo around the world, as people try and understand how someone so young could admit such a disgusting crime”, Baird said.
