Police say mental health professionals in Australia are frightened of being attacked, after the murder of a leading mental health service administrator. At least one meeting of mental health staff has recently been held under armed guard.
Detectives have widened their inquiries around the country and even overseas after the stalking and shooting four times in the back of Dr Margaret Tobin, aged 50, at her offices in Adelaide on 15 October.
Dr Tobin, the director of the South Australian mental health services, was gunned down on the eighth floor of the office building after the killer got into the lift, along with Dr Tobin and two other people, on the ground floor.
Police officers confirmed they were looking at her career as a psychiatrist and administrator in hospitals in Victoria and as a former mental health director for southeastern Sydney before she moved to Adelaide in July 2000.
