Police in Australia have seized new evidence and questioned five more doctors over last week's failed car bomb attacks in the UK, BBC reported.
Computers and other materials were taken from four Western Australian hospitals, two in Perth and two in the Outback mining town of Kalgoorlie.
Police said the doctors questioned had not been charged or 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.
