The Australian Federal Police has confirmed it is investigating an alleged security breach.
Reports have suggested a senior officer has been suspended after consulting a psychic during an investigation into a threat to assasinate the Prime Minister, John Howard.
Labor's Homeland Security spokesman, Arch Bevis says the investigation should be made public.
Mr Bevis says while there may be a humorous side to the issue, it's a serious matter.
"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."
"The public need to have their confidence in the AFP maintained by knowing what's happened here."
