PETALING JAYA (THE STAR/ASIA NEWS NETWORK) - Six bank accounts linked to the allegations of the channelling of funds to Malaysian Prime Minister Najib Razak have been frozen.

In a joint statement, the special task force which was formed to probe the allegations, stated that the order to freeze the accounts was issued on July 6.

"The special task force has also obtained documents on 17 accounts in two banks to assist investigations. Several documents pertaining to not complying with Bank Negara Malaysia's rules and procedures were also seized," the statement said.

As investigations are still under way, the task force has urged all parties to give their cooperation to allow for the probe to be completed.

The statement was issued jointly by Attorney-General Tan Sri Abdul Gani Patail, Bank Negara Malaysia Governor Tan Sri Zeti Akhtar Aziz, Inspector-General of Police Tan Sri Khalid Abu Bakar and Malaysian Anti-Corruption Commission chief commissioner Tan Sri Abu Kassim Mohamed.

The Wall Street Journal and the Sarawak Report website published an article on Friday quoting an "unnamed investigator", claiming that almost US$700 million (S$946 million) of troubled state investment agency 1Malaysia Development Berhad's (1MDB) funds went into Mr Najib's personal accounts.

The Prime Minister's Office responded by saying that the articles were "political sabotage", while the 1MDB insisted that no funds had been transferred to Mr Najib's accounts.

Mr Najib had also refuted the claims, maintaining that the allegations are a political ploy engineered by his opponents in an attempt to topple him.
