KEY POINTS:
Federal police raided two West Australian hospitals yesterday and questioned a further five doctors as the investigation into the foiled terrorist bombings in Britain spread to three Australian states.
Four Indian doctors in WA have been questioned while another overseas doctor in New South Wales was being interviewed by counter-terrorism police in the wake of this week's arrest of Gold Coast-based doctor Mohammed Haneef.
Seven people have been arrested in Britain, all of them doctors or with medical links.
Police are now checking 31,000 documents in relation to the operation, said Police Commissioner Mick Keelty.
"As part of the ongoing investigation, we have now, with the Western Australian police, executed warrants in Kalgoorlie, at the hospital, and also at the Royal Perth Hospital.
"A total of four search warrants have been executed in Western Australia," Mr Keelty said.
"The people we are trying to talk to at the moment, we are trying to gather evidence or information about the network, about who is linked to who and whether in fact anybody has committed any criminal offence."
