Men charged over Sydney backyard shooting

Four men have been charged after one of them shot at armed attackers who'd jumped the back fence of their western Sydney home.

NSW Police say a group of men armed with rifles and a shotgun jumped the fence in Revesby on November 25 and threatened a 35-year-old occupant as well as three men aged 21, 22 and 32.

The 35-year-old allegedly ran inside and picked up a rifle before firing several shots at the armed men who fled. No one was injured and the gang remains on the run.

The alleged shooter was arrested and charged on Wednesday following an extensive investigation.

Detectives say they found a firearm conversion kit and ammunition at another property in Revesby when arresting the man.

The 35-year-old was charged with shooting at a person with intent to murder, firing a weapon in a public place and other weapons charges.

The other men - aged 21, 22 and 32 - were on Thursday morning arrested in Panania, Bankstown and Balmain.

They were subsequently charged with being accessories after the fact to the shooting.
