The Malaysian attorney general's office said on Thursday it had reviewed the report of a central bank investigation into troubled state fund 1MDB and decided that fund officials had not committed any offence.
The statement comes in response to rare intervention in public affairs by Malaysia's royal rulers who called for a quick and transparent investigation into 1Malaysia Development Berhad (1MDB), adding pressure on the scandal-hit government of Prime Minister Najib Razak.
1MDB, whose advisory board is chaired by Najib, has amassed debt of more than $11 billion and is at the center of a political storm after allegations of graft.
In July, media reported that investigators looking into 1MDB had identified a payment of nearly $700 million into a bank account under Najib's name. Reuters has not independently verified the report.
Najib has denied taking any money for personal gain and the government has said the deposit was a private donation.
