Queensland’s fraud squad is being investigated by the state’s Crime and Corruption Commission (CCC) after media reports of corruption.

Detective Superintendent Brian Hay attended and organised fraud and cyber crime symposiums as well as appeared frequently on TV and radio in his former role as fraud squad leader.

But he surprised many when he announced he was stepping aside for a 12-month “career break” after 12 years in the job.

Since then it has been revealed that Superintendent Hay was the subject of a misconduct investigation after claims he misused a corporate credit card; a case that Queensland's corruption watchdog took over in July.

Reports say that when the ABC lodged Right to Information requests for documents relating to the corporate activities of Superintendent Hay, the Queensland Police Service (QPS) refused because the material was the subject of an investigation.

A statement from the QPS allegedly said; “[The QPS Ethical Standards Command], on behalf of the CCC, is investigating an allegation that, if proven, could comprise corrupt conduct”.

“The matter falls within parameters of your access application.

“The documents to which this application refers, have and continue to be utilised by the CCC in their assessment of the complaint and subsequent investigation,” they said.

The police said their investigations were ongoing, but that “no evidence of impropriety has been identified on any member of the QPS for misuse of a corporate credit card”.

Still, the story has added to already intense pressure on the QPS over the handling of fraud complaints.

The fire has been stoked by revelations that the CCC was assessing claims that the fraud squad failed to follow-up on claims of a kidnap plot involving Clive Palmer's associate and media adviser, Andrew Crook, dodgy former cop Mick Featherstone and developer Tony Smith, a former Sydney Swans AFL player. 

A number of men were charged in late 2014 by police anti-bikie taskforce Maxima over the alleged detention and coercion of a National Australia Bank (NAB) executive on an Indonesian island.

Additionally, reports have criticised the authorities for not following-up on a complaint made by the National Australia Bank that one of its executives had been kidnapped on an Indonesian island.

It appears that no investigation was launched until two years after NAB raised the issue.

And finally, media outlets have made allegations that the Queensland fraud squad also failed to act on multiple complaints from victims of ‘boiler-room’ investment scams on the Gold Coast, and that the CCC was looking into claims that the boiler-room syndicates were protected by corrupt former police.

Queensland's independent Commission of Inquiry into Organised Crime - established by the Palaszczuk Government – says it is looking into the alleged failure of police to investigate these claims.
