Second man accused of supplying weapon in Curtis Cheng murder denied bail

A second Sydney man accused of aiding and abetting the fatal shooting of NSW Police account Curtis Cheng has been denied bail in court.

Talal Alameddine, 22, was charged with supplying the gun that Sydney teenager Farhad Jabar used to kill Mr Cheng, breaching a firearms prohibition order and hindering police.

He was refused bail on Friday and will appear in court on December 10.

Co-accused Raban Alou, 18, was also held by police for more than a week before he was charged late Thursday over the shooting of Mr Cheng outside police headquarters in Parramatta on October 2.

He did not appear when his matter was mentioned at Sydney's Central Local Court on Friday and did not apply for bail.

Speaking outside court Mr Alou's lawyer Moustafa Kheir said his client would be fighting the accusations.

The teenager, he told reporters, was charged after being "held for more than 200 hours for the purpose of interrogation".

"The evidence that the charges rely on are circumstantial evidence. This means there is no direct evidence.

"Raban will be fighting these charges."

Police will allege Mr Alou sourced the handgun for Jabar, committing a terrorist act over a seven-hour period on October 2 between 9.30am and 4.35pm in Parramatta, court documents reveal.

In that period, it will be alleged Mr Alou met with Middle Eastern crime world figure Talal Alameddine and procured the old-style handgun for Jabar, a former school mate from Arthur Phillip High School. It will be alleged he spent two hours preparing the boy to carry out the murder.

On the day his family's western Sydney home was raided last year and his older brother detained as part of a counter-terrorism operation, Mr Alou spoke out about his anger on a perceived war on Islam.

"I dunno, I got a lot of anger," he told Fairfax after his home was raided on September 18, 2014.

"It's a war on Islam just because we grow our beards. They want to label us as a terrorist, or supporters of Islamic State, whatever, that's up to you."

Mr Alou, from Wentworthville, was charged last night with the Commonwealth offence of aiding, abetting, counselling and procuring the commission of a terrorist act and is due to appear at Central Local Court on Friday.

More details are expected to emerge about the two men who allegedly helped radicalise the young Jabar, encouraging him to carry out his attack.

It comes as police and government agencies float a terror plan encouraging parents who fear their children are falling under the spell of a terror group to call a helpline.

As part of the plan, schoolteachers will be enlisted to help spot children and youths at risk of becoming radicalised just as they might look for students suffering child abuse.

Police, security agencies and a wide group of State and Federal departmental chiefs met in Canberra yesterday to discuss ideas for countering the threat of violent extremism.

WA Police Commissioner Karl O’Callaghan said the conference was focused on prevention, rather than policing and justice-focused solutions.

“This really isn’t about the policing end of things, it’s about prevention and what we can do to give families of these people some assistance,” he said.

One plan put forward was to supplement the current national security hotline with a new counselling service that parents could access without going to police or security agencies.

Mr O’Callaghan said there needed to be limits set as to when the helpline should alert counterterrorism authorities that someone may be a threat.

He said school teachers could take an expanded role in spotting children with psychological problems.
