Police have searched a Melbourne medical clinic linked to a doctor suspected of infecting dozens of women with hepatitis C.
Anaesthetist Dr James Latham Peters was suspended from practice in February after 12 women he treated at the Croydon Day Surgery contracted the disease.
The ABC reports that a total of 41 cases have now been directly linked him.
Police are investigating whether they were deliberately infected by Dr Peters.
Police say they raided Doctor Peters' home, the clinic's two premises as well as the homes of two other staff members on Saturday.
New Zealand women who were treated at the clinic in 2008 and 2009 are among those who have since been tested.
