Australian police have searched two hospitals in Western Australia in connection with last week's failed car-bomb attacks in London and Glasgow.

Federal police commissioner Mick Keelty said police seized computer files and other materials from hospitals in the state capital Perth and the gold mining town of Kalgoorlie Friday.

The raids came after an Indian doctor was arrested Monday in the eastern Australian city of Brisbane. The 27-year old Mohamed Haneef is one of eight suspects who are all doctors or worked for Britain's national health service. He is the only one held outside Britain.

Australian police said their investigation into the British bomb plot has widened into a third state, New South Wales, where several foreign doctors are being questioned Friday.
