The Australian Federal Police has confirmed it is investigating an alleged security breach over a threat to assassinate Prime Minister John Howard.
Reports have suggested a senior officer has been suspended after consulting a psychic during the investigation.
Labor's Homeland Security spokesman, Arch Bevis says it's a serious matter and the investigation should be made public.
"It's obviously not part of standard operating procedure to consult a psychic about death threats to senior figures in Australia and the government really needs to have an open investigation into this so the public need to have their confidence in the AFP maintained by knowing what's happened here."
