Police have released CCTV images as they search for four men and a woman over a deadly shooting in Brisbane's south-west yesterday.

Detective Inspector Andrew Massingham said yesterday up to four males and one female attended the residence and allegedly started assaulting a man who lives there.

"At that time, the male deceased was seated in his vehicle directly opposite the address. Upon seeing it occur, the deceased left his vehicle and confronted the persons in the front yard," Massingham said.

Massingham said the group was armed with at least two guns, including a shotgun and potentially a handgun.

"The male deceased was struck at very close range, and we believe the weapon involved was a 12-gauge shotgun," Massingham said.

Massingham said it's not clear how the five people involved left the scene.

"We believe possibly in a vehicle but we are desperately seeking public assistance for any person who saw movement in this area around 3.25am," he said.

Massingham revealed the resident inside the home who was allegedly assaulted, the deceased man and the offenders have "been involved in a dispute".

"It has been occurring for some time," he said.
