Two alleged members of the Lone Wolf motorcycle club remain behind bars after being accused of brazenly murdering former Comanchero bikie boss Mahmoud "Mick" Hawi for money.
Hawi was shot multiple times and his luxury four-wheel-drive was peppered with bullets as he sat in the vehicle outside a Rockdale gym, in Sydney's south, in February.
Police claim the alleged killers, Yusuf Guney Nazlioglu and Ahmad Doudar, had a financial motive and Hawi's killing meant he didn't have to be paid further money.
The debt "related to a construction industry as opposed to any specific person", NSW Police Assistant Commissioner Malcolm Lanyon said on Saturday.
"It's the fact that people are brazen enough to be prepared to murder an individual for an amount of money that we find so appalling," he told reporters in Sydney.
Nazlioglu, 37, and Doudar, 38, didn't apply for bail and it was formally refused during their first court mention on Saturday.
Their lawyer Leo Premutico said they're expected to make a release application when they appear in Central Local Court next week.
The third man charged with being an accessary after the killing, 36-year-old Moustafa Salami, will also seek bail when he faces court on Tuesday.
The trio's arrests on Friday came after police raided six properties across Sydney earlier in August in relation to the killing, seizing several cars.
Police at the time warned those responsible for Hawi's death that they were closing in on them
"At the moment we would say there would be a number of people feeling very uncomfortable, and we would like them to feel uncomfortable," Detective Superintendent Deb Wallace said.
Assistant Commissioner Lanyon on Saturday said the investigation was ongoing and more arrests were expected.
Hawi at the time of his death had mainly flown under the radar following his release from prison in 2015.
He'd been jailed over the 2009 bashing death of Hell's Angels associate Anthony Zervas in a wild brawl at Sydney Airport.
Assistant Commissioner Lanyon said members of outlaw bikie gangs were typically members for life, so Hawi would still have been "well and truly associated" with the Comancheros.
However, his killing is not alleged to be linked with "any traditional outlaw motorcycle gang conflict".
