Sydney, Sept.8 : Australian Federal Police Commissioner Mick Keelty was reportedly grilled for three-and-a-half-hours on Monday with regard to evidence connected to the bungled investigation of Indian doctor Mohamed Haneef.
As he left the hearing, Keelty told reporters only that he had "cooperated fully with the inquiry" by retired NSW Supreme Court judge John Clarke.
Dr Haneef was arrested by federal police at Brisbane Airport in July last year in relation to an attack by Islamist militants in Britain.
The investigation slowly unravelled and Dr Haneef was eventually released without charge.
"I look forward to making some public statements once the inquiry delivers its findings," said Keelty, whose evidence was given in camera.
Asked if the police had made any mistakes in the investigation, Keelty told reporters that was a matter for "the inquiry to determine".
Keelty has been under intense pressure in recent months because of the failed case but he recently received an endorsement from Attorney-General Robert McClelland.
Dr Haneef is now working in Dubai, although Queensland Health Minister Stephen Robertson has delivered an invitation for him to return to the sunshine state.
"From our perspective, there are no outstanding issues," Robertson told ABC Radio last week.
"My personal view is I think he's been treated absolutely appallingly. Certainly the Gold Coast health district has always held him in high regard," he added.
Paul O'Sullivan, head of the Australian Security Intelligence Organisation, is due to give evidence to the inquiry tomorrow.
In an unclassified submission to the inquiry last month, O'Sullivan revealed ASIO had believed there were no grounds on which to charge Dr Haneef.
