The incidents have been outlined in the NSW Supreme Court as police seek to impose sweeping orders on members of the Hamzy and Alameddine families to prevent further violent reprisals following the killing of Mejid on October 19.
The court is considering whether to grant the police applications for serious crime prevention orders against Ibrahim Hamzy and Ghassan Amoun,the brother of Bassam and Mejid. In separate proceedings,police are also seeking an order against Rafat Alameddine.

The orders would impose stringent conditions,including whom the men can speak to,where they can go and their phone use. They must also divulge details of their vehicles,bank accounts and online accounts.
In a hearing on Tuesday,NSW Police attempted to demonstrate that the orders were needed to restrict the activities of the men and reduce the risk to crime figures and members of the public.
Barrister Lachlan Gyles,SC,representing NSW Police,linked the violence to an escalating dispute over drugs.
He said the police were targeting men who"have their own interests in retribution"because they have been targeted or had a family member slain during the dispute.
