Police reveal new details in gunman incident
2.50PM: THE WEAPONS used by the alleged gunman were licensed to a relative, police have confirmed.
Detective Inspector Brendan Smith said police will allege Troy Dean Sprigg, 29, of Sarina, stole the rifles from a family member.
It is also alleged he fired at least six shots, a few into his car and then into the air. At least one bullet hit a building on Gregory St.
At one point 15 to 20 police officers were on scene, including Sergeant Tasman Place, who was one of the first to respond.
Sgt Place explained that police did not confront Sprigg because they had the "luxury of time".
"We then engaged in a prolong negotiation with him," he said.
"We don't like to rush these things, once the CBD was closed we had the luxury of time, so we didn't want to rush."

Queensland Police have revealed the man at the centre of the incident, now identified as Troy Dean Sprigg, allegedly fired up to eight rounds, with one shot hitting a building.
