The Australian police has decided not to seek further detention of Indian doctor Mohammed Haneef, currently being investigated in connection with the failed UK terror plot, media reports said on Friday.

Haneef, who has been in custody for 11 days, is yet to be charged with any offence.

'The Australian Federal Police has decided not to proceed with their application to extend the detention period of Gold Coast-based doctor Mohammed Haneef,' the Australian Broadcasting Corporation said.

AFP officers now have 12 hours to question Haneef, excluding usual break times such as meals, it said. 

Police have not been able to find any 'incriminating' evidence against Indian doctor Mohammed Haneef detained in connection with the UK terror plot, another media report claimed on Friday.

Haneef has told AFP of his family ties and telephone contact with accused suicide bomber Khafeel Ahmed, and revealed how they shared a house in the British city of Liverpool for up to two years, the Australian newspaper said.

'Police have been unable to find any evidence against Gold Coast Hospital terror suspect Haneef to justify charges despite executing several search warrants in a massive investigation over the past 10 days,' it said.

Current documents circulated by senior public servants in the Howard government show the AFP acknowledges that while it has scant or no evidence against Haneef, agents still suspect he has 'provided support to the terrorist organisation responsible for terrorist acts in London [Images] and/or Glasgow during 29 and 30 June, 2007.'

Haneef is a second cousin of Ahmed, who is allegedly involved in the failed attempt to blow up Glasgow airport with a burning Jeep Cherokee.

The AFP has been delaying further formal questioning of Haneef, 27, because without incriminating evidence, which officers still hope to obtain from a vast volume of material, they cannot test his knowledge.

'But so far AFP's searches have come up with blanks. And calls for Haneef's immediate release are growing louder. The documentation known to the Australian refers to police suspicions, relations, connections, phone numbers, borrowed phone cards and overseas terrorism,' the paper said.

'But nowhere does it confirm any finding yet of sufficient substance to justify charging Haneef, who is spending his spare time in prayer,' it said.

Seized materials include 1,636 photographs, a 40-gigabyte hard drive that belongs to Haneef, an 80-gigabyte hard drive belonging to his friend and fellow Gold Coast doctor Mohammed Asif Ali, two mobile telephones, a personal digital assistant, two 128-megabyte flash drives, a Cybershot digital camera, documents including email addresses, clothing, computer discs, a global positioning system and phone packaging, the newspaper said quoting documents obtained by it.

'Investigations are complicated by the need to interrogate these computer hard drives -- significant resources have been committed to this analysis resulting in approximately 95 per cent of material being examined to date,' it said.

The documents show the AFP also suspects 'Haneef has not been entirely truthful in relation to the information he has provided police in relation to his attempt to leave Australia.'

While British authorities have been provided with 'Australian holdings on Haneef for cross-analysis in an attempt to identify commonalities with the UK investigation,' the volume of data in both countries will take 'a significant period to analyse,' it said.

Meawhile, his lawyer Peter Russo revealed that Haneef went through a DNA test on Friday.

"The tests were merely a routine procedure," he said.

Vicky Nanjappa adds from Bangalore:

The family of Dr Haneef Mohammed said they were unaware of when he would reach Bangalore.

The only communication they have received so far is that he would be released soon, but that he may not be able to come to India immediately as he would be required for some more questioning.

There was obvious happiness in the Mohammad household over the news of his detention not being extended.

Haneef's wife Sumaiyya and mother Qurrainthullain said their prayers have been answered and that he has been declared innocent.

Woman released:

Marwa Asha, the only woman among eight suspects arrested by British police investigating the botched London and Glasgow bomb plots, has been released without charge, a Scotland Yard spokesman said.

Marwa was arrested along with her doctor husband Mohammed Asha on the M6 motorway in Cheshire on June 30, hours after a blazing jeep crashed into the terminal building of Glasgow airport.
