Indian doctor Mohammed Haneef, arrested Monday at Brisbane Airport over last week’s failed car bombings in London and Glasgow, will be questioned by a senior British police detective Thursday.

Australian authorities arrested Mohammed Haneef, 27, Monday night at Brisbane Airport, where he was waiting for his flight to Bangalore, India, on a one-way ticket. They had been tipped by British police investigating last week’s attempted car bombings in London and Glasgow.

Haneef has been in custody ever since arrest, on suspicion that he is connected with the attacks due to his connection with one of the other suspects, held in Britain. British police tracked him through phone call records.

Recent investigations show that Haneef and Sabeel Ahmed, 26, a suspect arrested in Liverpool over the botched bombings, trained in the same Bangalore medical institute. All eight suspects arrested have a medical background; seven are doctors, one is a health technician.

All eight detainees have worked in British hospitals. Haneef and Ahmed worked in a Liverpool hospital until last year, when Haneef moved to Queensland, Australia and got a job at Gold Coast Hospital.

Members of Haneef’s family as well as friends and former colleagues from school told Indian media that Haneef was coming home to see his baby girl of ten days, in some emergency, as the baby had jaundice.

They told the Times of India that Haneef had always been a hard worker and a good student and that he had no fundamentalist leanings.

The senior police detective to question Haneef is a chief inspector from Scotland Yard's counterterrorism unit.

Federal Police Commissioner Mick Keelty said that British authorities had not sought Haneef's extradition. Keelty added that he expected Haneef to be either charged or freed before the end of the week.
