Queensland’s police minister says anyone with evidence of impropriety should come forward over allegations against former police Commissioner Bob Atkinson.

Queensland’s former police commissioner is under scrutiny over allegations he helped his wife secure a research grant without declaring a conflict of interest.

Police Minister Jack Dempsey urged anyone to come forward if they had any evidence to back up the allegations.

“These matters occurred nearly 10 years ago and I do encourage past and present officers, or any other members of the community, who have any evidence of any impropriety to please report any matters to the CMC,” he said.

Seven News on Thursday night showed Mr Atkinson backed the $366,000 grant involving his wife Glenda Adkins, and found no evidence he declared a conflict of interest.

The federally-funded National Drug Law Enforcement Research Fund approved the project in 2004 which promised to identify an approach which was most likely to substantially erode criminal industry profits from the drug trade.

Dr Adkins’ business address was listed as “c/o Commissioner Bob Atkinson” at Queensland Police Headquarters, and he signed his agency’s support of the project, which was needed to secure the funding.

The couple deny any wrongdoing.

Despite promising to deliver the report after three years, Dr Adkins didn’t produce a publishable report and the NDLERF has since written off its investment.

A police spokeswoman told AAP former Commissioner Atkinson did not have a role in any approval of, the conduct of, or funding of the project.

She said the project was to be conducted by the Queensland University of Technology and Dr Adkins applied for the grant with two others.

The research benefited the community and the Queensland Police Service, the spokeswoman said.

“The Queensland Police Service routinely supports and participates in research matters where there is no direct financial input from the service,” a spokeswoman said.

“Perceived conflicts of interest regarding this matter are for consideration by other parties.”
