MELBOURNE, July 14 (Reuters) - Australian Federal Police said on Saturday they had charged a 27-year-old Indian doctor over his alleged links to attempted car bomb attacks in Britain on June 29 and 30.

Mohamed Haneef was charged with providing support to a terrorist organisation, police said. He is due to appear in court in Brisbane later on Saturday.

The Queensland-based doctor had been held for 12 days and police withdrew a request on Friday afternoon to extend his detention, and began 12 hours of questioning.

Australian Federal Police Commissioner Mick Keelty said the police charge cited recklessness, rather than intention. "The allegation being that he was reckless about some of the support he provided to that group, in particular, the provision of his (mobile phone) SIM card for the use of the group."

Haneef is one of six Indian doctors questioned in Australia over the suspected al Qaeda-linked plot in Britain. The others have been released. Haneef could face up to 15 years in prison if convicted.

Keelty said the charges came after 12 days of investigation, with almost 300 police and lawyers working on the case, sifting through the equivalent of 36,000 four-drawer filing cabinets of material.

"That is the quantity of material that has been seized in electronic form, from various locations," Keelty told reporters in Canberra.

Two car bombs primed to explode in London's bustling theatre and nightclub district were discovered early on June 29. The following day a jeep crashed into the terminal building at Glasgow airport in Scotland and burst into flames.OPPOSING BAIL

Haneef's lawyer Peter Russo told Australian radio that Haneef was "very upset" by the news and would apply for bail.

Keelty said police would oppose bail and it remained to be seen whether police in Britain had any evidence to support an extradition request.

Australian anti-terrorism laws allow police 24 hours of questioning. They had only used 12 hours by Friday, and restarted questioning early on Saturday.

Haneef was detained at Brisbane airport on July 2 as he was about to board a flight to India.

All six suspects in Britain are medics from the Middle East or India. One, Iraqi-trained doctor Bilal Abdulla, 27, was charged last week with conspiring to cause explosions.

Haneef is a second cousin to Kafeel Ahmed, a suspect who is in a critical condition with burns from the Glasgow attack, and last contacted him via the Internet in March/April 2007, police documents cited by The Australian newspaper said.

The documents said Haneef was not very close to his cousin, but stayed with him and other suspects when he visited Britain in 2004. When Haneef left Britain in 2006 to travel to Australia to work, he left his mobile telephone SIM card, which one of the suspects later used to access a cheaper telephone deal.
