Papua New Guinea's opposition is demanding answers on why an Indonesian fugitive wanted by Interpol was granted citizenship in June.
Djoko Tjandra has been on the run from Indonesian authorities since 2009 after allegedly embezzling millions in bailout funds from the now defunct Bank of Bali.
Mr Tjandra reportedly fled Indonesia a day before the country's Supreme court sentenced the now 62 year old in absentia to two years jail.
The PNG Prime Minister Peter O'Neill told Parliament last Friday he had been advised there were irregularities in the granting of citizenship to Mr Tjandra and an investigation is underway.
Mr O'Neill says he will raise the issue with Indonesian president Susilo Bambang Yudhoyono at a scheduled meeting in late November.
The Opposition Leader Belden Namah has urged the government to come clean on why Mr Tjandra was granted citizenship in the first place.
