Police shot dead his attacker, 15-year-old Farhad Jaber, at the scene.
They were interviewed about the shooting murder of Mr Cheng by 15-year-old Farhad Khalil Mohammad Jabar outside the Parramatta police headquarters on Friday.
He will tell those kneeling upon the tattered red carpet that enough is enough; the mosque is no place for politics, it is a place for worship.
“Get out. We do not need scumbags in the community”.
It comes a week after a teenager from the same school shot and killed a police force veteran of 17 years, Curtis Cheng.
“There’s no doubt we have to do more”, he said. “The rose is handsome, but the spike will sting you”. “On the contrary, it should serve to unite Australians to affirm all the more strongly the values that our society has always held dear, and to do so in our politics, our educational institutions, our media and every facet of our public life”.
Greg Barnes from the Australian Lawyers Alliance said the teenager’s detention was “extremely concerning” for several reasons. “If you don’t like it, leave”.
Parramatta Mosque leader Neil El-Kadomi claimed the CCTV vision given to police showed the teen gunman wearing a tracksuit and praying alone at the mosque Âbetween 11am and 11.40am – and that he had not been wearing a backpack at the time.
But New South Wales Police Deputy Commissioner Catherine Burn said Jabar was not on the radar of security services.
“My message to those who would consider committing an act of violence is it will not be tolerated”.
Ms Scott said a united effort was needed to find a solution and the Islamic community was coming on board.
The sermon lasted about 30 minutes and afterward Mr El-Kadomi took questions in a smaller room inside the mosque.
“They seek to identify vulnerable people…to carry out a terror attack in here in Australia”, he told the Seven Network on Thursday. But the pressure has been building for the past 12 months.
Police have arrested five people in a series of raids in connection with the terror-linked killing of a civilian police worker.
“If you don’t like it, get lost”, he said.
However, Kadomi has criticised the protest organised by anti-Muslim groups, asking, “If somebody walks into McDonald’s and shoots everyone, is McDonald’s blamed?” A 16-year-old, who can’t be named, was released on Wednesday night without charge.
Justice Minister Michael Keenan said the government was working hard to stop young people becoming influenced by radical extremism.
