In yet another embarrassment to Australian police, it was on Monday revealed that investigating officers wrote the names of overseas terror suspects in Indian doctor Mohammed Haneef's personal diary and later grilled him during an interrogation over whether he had written the notes.

The revelation came hours after AFP chief Mick Keelty dismissed reports of Haneef's suspected involvement in a plot to attack the Gold Coast's tallest building.

The report in The Australian stated that investigating AFP officers wrote the names of overseas terror suspects in Haneef's personal diary, only to later grill him during an interrogation over whether he had written the potentially incriminating notes.

The mistake was revealed in the record of the first interview between Haneef and two officers from the AFP's counter-terrorism force, Queensland Detective Sergeant Adam Simms and federal agent Neil Thompson.

Towards the end of the interview, which occurred soon after Haneef was arrested at Brisbane International Airport on July 2 for allegedly providing support to a terrorist organisation, Sergeant Simms states: "In your diary, you had handwritten notes. Is this your writing?"

Haneef responded "No. This is not my writing. Definitely not."

After suspending the interview, the officers returned to the question of the handwritten notes, including the name and contact details of an alleged suicide bomber Kafeel Ahmed, a second-cousin of Haneef.
