A man produced a firearm and fired a shot towards a good Samaritan who tried to stop him violently assaulting a woman on a Sydney street, police allege.
After Ellias Khouri, 29, fled police with another man, their utility ran a red light and collided with a Suzuki Swift, according to a statement of alleged facts tendered in court.
The 43-year-old driver of the Swift, who also had a child in her car, was seriously injured in the Friday morning crash in south-west Sydney.
The alleged gunman and utility driver were both denied bail during their first mentions in a Parramatta court on Saturday.
Court documents allege James George Scicluna, 36, helped Khouri try to evade police after the 29-year-old assaulted a woman on a Leppington street and shot towards a resident who tried to intervene.
Police say they'd called off a pursuit of Khouri's Subaru WRX over safety concerns when the utility driven by Scicluna allegedly ran a red light and collided with the Swift.
Khouri kicked out a window from the passenger seat of the badly-damaged utility before he was arrested with a loaded gun down his underpants, according to the alleged facts tendered in Scicluna's case.
Khouri, from Beverly Hills, didn't appear in court or apply for bail during his first mention on Saturday, and it was formally refused by the magistrate.
An emotional Scicluna, who appeared via video link during his unsuccessful release application, said "I'm so sorry" as his pregnant partner sobbed in the public gallery.
The Oran Park resident is expected to face court again on Tuesday, while Khouri's next mention is listed for October.
