The police investigation began after a formal complaint from the South Fly MP, James Donal.
In a statement issued on Thursday, the PNG police commissioner, David Manning, said investigations were continuing and “other suspects will also be brought in for inquiry into their alleged involvement in committing the fraud”.
“The investigation remains ongoing and includes a detailed forensic investigation into ... the expenditure of the 268m kina, which police will allege were not authorised by the trust … this includes forwarding proceeds from the 268m kina to personal bank accounts.”
Earlier this month, 45-year-old Edna Oai, from South Fly district in Western Province, was charged with 15 counts of false pretence, conspiracy and misappropriation over the alleged fraud.
