A local business owner, who did not want to be named, was not surprised a gun was involved.
''They've been used before, so they definitely have them stashed somewhere."
The owner said an increased police presence is the only way locals feel safe enough to venture outside.
"An increase in police in Taradale is a great thing – it's the only way people in the area are going to feel safe."
Anyone with information that can help police is asked to contact 105 and quote event number P044506340.
Sunday's incident was within one kilometre of a mass brawl involving 30 to 40 Black Power and Mongrel Mob members in January.
A 25-year-old man was seriously injured by a gunshot during the incident, while a pellet also struck the back of a child's car seat while a child was sitting in it.
Meanwhile, two people were injured after a gang dispute outside The Thirsty Whale Bar and Restaurant on Sunday morning.
