A second Indian doctor who was detained along with Mohammed Haneef in Brisbane in connection with the UK terror plots has been released after questioning while Haneef's detention has been extended.
Mohammed Asif Ali, 26, was released without charge after being questioned by Australian Federal Police over bomb plots in London and Glasgow.
Australian Federal Police Commissioner Mick Keelty on Wednesday said Ali had not committed any crime and was free to go about his business.
"As with a lot of investigations, a lot of people are spoken to and he's now back in the community," Keelty said adding "there is nothing to suggest he has committed any offences at this point in time."
Australian police have been granted an extra two days time to interrogate the Indian doctor detained in connection with last week's failed terror attack in the UK, Prime Minister John Howard said.
Howard said Britain is sending a top police officer to Australia to question 27-year-old Haneef.
Ali told the media today that he was extremely tired after the ordeal and just wanted to sleep.
He was interviewed following Haneef's arrest by federal police on Monday night.
He and Haneef both previously worked in Liverpool, England, where they also lived together. Both were trained in India, The Age said.
