Police in Australia have seized new evidence and questioned five more doctors over the failed car bomb attacks in Britain
Computers and other materials were taken from two Western Australian hospitals, one in Perth and one in the Outback mining town of Kalgoorlie.
Police said the doctors questioned had not been arrested.
The raids came as Australian police were given more time to question a relative of two men held in the UK.
Mohammed Haneef was held at Brisbane airport in Queensland as he tried to leave for India on Monday. He will be questioned by a team that includes a senior counter-terrorism officer from Scotland Yard.
Eight people, all linked to Britain's National Health Service, have been arrested over the failed attacks in Glasgow and London.
Australia's federal police chief Mick Keelty said the new people quizzed were "migrant doctors, of similar nationality and background to the other doctors that are being questioned".
