Queensland’s corruption watchdog will review the police handling of a recent case that struggled to pass the sniff test.

Queensland Police whistleblower Sergeant Rick Flori leaked CCTV footage of a man being bashed while handcuffed in the back of a police van in the basement of the Surfers Paradise police station in 2012.

In a mind-numbing subversion of natural justice, Sergeant Flori has been charged for the leak, and now faces a possible seven years' jail.

The footage shows four officers involved. They are seen throwing the handcuffed Mr Begic to the ground, moving him to the back of the van, holding him up and repeatedly punching him, then taking him away and using a bucket of water to wash his blood off the concrete.

Reports say the men who carried out the bashing were subject to an internal police investigation and have since resigned, been disciplined, or “educated”.

Mr Flori, the man who brought the brutal police assault to light, has been charged with one count of criminal misconduct in public office.

Council of Civil Liberties deputy president Terry O'Gorman has put in a “public interest complaint” to Queensland’s Crime and Corruption Commission [CCC] on how Sergeant Flori was treated.

O'Gorman says he wants to know why Sergeant Flori was charged, but the officers who bashed Mr Begic appears to have got off with a slap on the wrist.

The CCC 2012–13 annual report revealed that the watchdog signed-off on the police decision not to prosecute the police.

It says it will now review its own actions, and those of the Queensland Police.

“Having considered your submission, and the degree of community concern generated by the initial incident involving police, the CCC considers that it would be in the public interest for it to detail the way this matter has been dealt with by the CCC and the Queensland Police Service,” the CCC’s response to Mr Gorman said.

“The [CCC] were party to this decision not to prosecute these police,” Mr O'Gorman told the ABC.

“If the [CCC] were party to this decision, then I'm starting to get worried about the validity and practicality of the CCC now investigating themselves.”
