A BURMESE refugee who claims to have executed dozens of political activists while operating undercover in Burma says other former agents who worked with him are living in Australia.
Htoo Htoo Han, who is now an Australian citizen living in Brisbane, says he headed a group operating within Burmese military intelligence that infiltrated student groups.
Mr Han admits to killing at least 24 suspected dissidents and being indirectly involved in the deaths of more than 100 others.
Others have questioned Mr Han's state of mind, suggesting he couldn't have committed the atrocities he has admitted without it being more widely known.
He admits he has been treated for depression, but friends who have known him for many years in Australia say he hasn't shown signs of anything more serious.
Mr Han claims to have executed his victims during and after the 1988 protests in Burma against government oppression and economic mismanagement.
Federal Attorney-General Robert McLelland has referred the case, which he described as an "extremely serious matter", to the Australian Federal Police for investigation.
"Australia has a strong framework in place for protecting the Australian community from the perpetrators of war crimes, and for ensuring their proper investigation and prosecution," the attorney-general said in a statement.
Australian law provides comprehensive coverage for war crimes, crimes against humanity and genocide offences committed after 2002.
There are also limited powers to deal with offences committed before 2002.
