Police have doubled the reward to $500,000 to solve the attempted murder of Senior Constable Neill Scutts at Logan, in the state's southeast, in 1999.

"I would really like to see a resolve for this. I'd like to see the little pricks in jail and before the court," Sen Const Scutts told reporters on Monday.

"This has had a dramatic impact on my family at the time. Thankfully my two young girls weren't around at the time, but it did impact the rest of my extended family."

The violent chain of events began at 8.25am on March 24, 1999, when two men forced their way into a bank in Browns Plains and held everyone at gunpoint.

Two officers arrived soon after and Sen Const Scutts was shot in the groin as he walked into the building.

"My hands are in the air, I literally stuck my hands up like that, and (I was) shot, that was it. And the next thing I know I'm on the ground," he said.

When he fell to the ground one of the men stole his firearm, a Sturm Ruger .357 six-shot revolver, which has never been recovered.

"I was at risk of dying if it had hit my artery - I made a comment of some description in regards to they need to get me medical help and I was told to shut the f*** up," he said.

"That was as blunt as it got."

Meanwhile, the other officer had gone around the back of bank where he was shot at by the robbers inside the building and sprayed with glass fragments.

The offenders fled on foot, taking two staff members as hostages, and stole a car at gunpoint which was later found abandoned.

The men were wearing off-white plastic masks, surgical style gloves and carrying two-way radios.

Sen Const Scutts underwent emergency surgery when it was discovered the bullet had missed major arteries by millimetres.

"The fact that they had no remorse, no thought process, second thought process, in relation to shooting me gives an indication of how they believe or what value they put on any sort of life," he said.

"It could have easily been one of the hostages at the time.

"In a way I'm grateful it was me, not the hostages.

"However, I would have preferred it wasn't me for obvious reasons."

Assistant Commissioner Mike Condon has urged anyone with any information to come forward or call CrimeStoppers on 1800 333 000.

He said police would never give up on finding those responsible for the shooting.

"We've lost a lot of police over the years that have gone through these type of events and fortunately Neil's been able to have the courage and the strength and support of his workmates to continue on," Mr Condon said.
