The updates on the progress and outcomes of the investigations relating to 1Malaysia Development Bhd cannot be specific.
Attorney-General Tan Sri Mohamed Apandi Ali said that it would not be appropriate to divulge details that may compromise those investigations.
He said that media statements have also been issued by the Malaysian Anti-Corruption Commission on the arrest and remand of persons to assist in their investigations in the matter.
"More specifically, it would not be appropriate to disclose the advice, instructions, directions or guidances given to the investigating agencies.
"While the public is entitled to be informed, details of criminal investigations which comprise of, among other things, contents of statements given by witnesses are privileged and the law prohibits such matters to be disclosed," said the country's top prosecutor in a media statement.
He said the investigating agencies have issued media statements to provide general updates on developments in the investigations.
"This includes the raid on the offices of 1Malaysia Development Bhd at Menara IMC in Kuala Lumpur on July 8 and on the materials seized there," he said.
He said it is crucial to preserve the integrity of the investigation as the public must not doubt the investigation.
"It is appreciated that there is deep public interest and concern in the progress and outcome of the investigations relating to 1MDB," he added.
He was responding to the concerns raised the five independent oversight panels of the Malaysian Anti-Corruption Commission which stated that the 1MDB investigations should remain "independent and free from interference
In a joint statement on Thursday, the five panels had reiterated that the four agencies that make up the special taskforce investigating 1MDB - the Attorney-General's Chambers, police, Bank Negara Malaysia and MACC - should be given "the latitude to conduct the investigations without fear or favour".
"In this matter, we strongly feel that it is highly pertinent to ensure that the integrity of the MACC as an independent anti-corruption commission is maintained and not be compromised," said the statement jointly signed by the Special Committee on Corruption, the Anti-Corruption Advisory Board, Operations Review Panel, the Complaints Committee, and the Consultation and Corruption Prevention Panel, chaired respectively by Tan Sri Abu Zahar Ujang, Tunku Abdul Aziz Tunku Ibrahim, Tan Sri Hamid Bugo, Tan Sri Wilson Baya Dandot and Tan Sri Johan Jaaffar.
"The panels are unanimous in calling for a thorough investigation and for the findings to be made public as soon as possible. This is necessary in order to reduce the widening gap in the level of perception as well as confidence," it said, while also urging the Attorney-General to provide clear updates on developments in the investigations, even as he dispenses legal advice and guidance to the taskforce, so as to prevent the agencies from being perceived in a negative manner.
