Police say a man fatally shot another man with a sawn-off firearm in Maryland on Saturday afternoon after an earlier altercation between the pair.
Police arrested a 30-year-old man in the early hours of Sunday morning at an address in Wallsend and he was taken to Newcastle police station to help them with their inquiries.
He was later taken to John Hunter Hospital for treatment of unspecified injuries.
Neighbours in Beauford Avenue told the Newcastle Herald that they had heard a loud, single gunshot at about 4pm on Saturday afternoon.
Police say they arrived at the scene to find the 38-year-old victim lying dead in a garage.
Acting Inspector David Piddington, of Newcastle City Police District, told a media conference on Sunday morning that the shooting was not bikie-related.
“I can confirm that the people are known to each other. It is a targeted incident,” he said.
“I believe there’s a prior incident that’s occurred, so around about 4.10pm yesterday afternoon there’s been an incident at Beauford Avenue, Maryland.
“ … There were family present and a de facto.”
Acting Inspector Piddington said he did not believe the shooting was a payback but it was a “targeted offence” and there was no danger to the rest of the community.
He said the 30-year-old had been taken to hospital on Sunday to be treated for injuries police believe occurred on Saturday morning.
The man was arrested after specialist police and negotiators surrounded a home on Raglan Street, Wallsend, at 1am on Sunday.
The man and nine other people, including children, exited the house without incident at 3.45am.
Acting Inspector Piddington said police expected to lay charges against the 30-year-old man on Sunday afternoon.
They were searching for the weapon used in the shooting.
