SYDNEY, Nov 7 AAP - Suspected members of the notorious Brothers 4 Life are behind bars throughout Sydney on a landmark day for police, who believe the deadly gang will crumble.
Ten alleged gang members were charged over western Sydney shootings that have killed or injured other gang members.
Mohammed Hamzy, believed to be the de facto gang leader, was the police's biggest catch.
He was charged with murdering fellow gang member Yehyah Amood on October 14, 2012, at Greenacre.
The 28-year-old, who is the cousin of jailed gang founder Bassam Hamzy, faced Bankstown Local Court on Thursday.
He was also charged with shooting with intent to murder Bassam Hijazi.
As well, he is charged with discharging a firearm with intent to cause grievous bodily harm at Yagoona on October 8, 2012.
NSW Deputy Commissioner Nick Kaldas says police believe a split in the gang is responsible for the flare-up of violence.
"It's difficult to classify it as one type of conflict," he told reporters.
"Whether it's a power struggle or people simply being offended about something that's been said, and acting in a quite irrational way by shooting someone instead of arguing."
Two other gang members, one on crutches with "MEOC" tattooed on his neck and another revealed to be a Google software whiz with an injured nose, were refused bail in the same court.
In court it was revealed that Adam Dowidar, 25, who had a bandage on his nose, was no ordinary gangster, despite being accused of letting his car be used in the murder of Mr Amood and hindering the police investigation.
The court heard he had worked for years as a software engineer for Google Maps and earned $160,000 a year before his contract ended in May.
