Three Charged After Brisbane Doctor Gunned Down At His Home

Police have charged two teenagers and a young man with murder after a Brisbane doctor was gunned down at his home earlier this week.

Luping Zeng, 56, was packing his car in the garage of his MacGregor home when he was shot in the chest just before midnight on April 15, police said.

Zeng's wife and two adult children were at home at the time and rushed to try and save him, but he died in hospital a short time later.

A 17-year-old boy from Slacks Creek was arrested over the shooting death on Thursday afternoon in South Brisbane.

On Friday, a 19-year-old man from Kingston was arrested in Slacks Creek about 11am and a 20-year-old man was taken into custody in nearby Woodridge about 40 minutes later.

The three men have each been charged with one count of murder along with several other offences, including entering a dwelling with intent, attempted armed robbery and possessing shortened firearms.

Detective Superintendent Tony Fleming said the youngest man didn't know Zeng and robbery appeared to be the motive.

"It was likely this is a crime of opportunity that has escalated and resulted in the death of Dr Zeng," he told reporters on Friday.

He said the three alleged killers are known to each other.

The arrests come as police released images of a silver 2013 Hyundai Elantra hatchback possibly bearing false Queensland registration plates 078YPN.

Fleming appealed to anyone who has seen or has dashcam footage of the car to come forward.

The 17 year old was remanded in custody while the two older men are expected to appear at Brisbane Magistrates Court on Saturday.
