UPDATE 3.15PM: AS THE SOUND of gunshots and sirens pierced the air in Fields St, South Mackay resident Troy Higley ran outside to find out what was happening.
Mr Higley, was visibly shocked as he explained the drama that unfolded across from his Field St home where a man reportedly suffered a gunshot wound.
Mr Higley said he was at home getting changed to go out when police and ambulance crews descended on the area.
"I heard all these sirens across the road, I came outside and looked and saw police everywhere, two ambulances, detective cars and unmarked cars all sort of pounced on the house across the road in the paddock,' Mr Higley said.
"I asked the officer walking up and down the street here what was going on and he said he couldn't tell me anything."
Mr Higley said from he had observed some strange goings-on in the area over the last couple of months.
"I have seen different types of cars going in and out across the paddock. Parking outs the front of the fence and I thought maybe they were renovating or maybe it was just visitors.
"I didn't hear any shots, all I heard was the sirens but it looks like someone has been injured because I saw someone come out on a stretcher."
Mr Higley, who has lived in the street for 20 years, said it was usually a nice, safe neighbourhood.
"We've never had any problem with crime. This spooks people. It is a quiet neighbourhood with elderly and everyone minds their own business but when something like this happens, of course you are going to come out and find out what's going on, we are concerned," he said.
