KUALA LUMPUR, Sept 2 — Troubled state-owned firm 1Malaysia Development Berhad (1MDB) today denied any knowledge of its bank accounts in Switzerland being frozen.

In a brief statement, the investment fund said that as far as they are aware none of their bank accounts had been frozen.

“1MDB is in the process of developing a better understanding of the on-going investigations in Switzerland so the company can cooperate to its fullest extent,” it said.

Earlier today, newswire Reuters reported Swiss authorities confirming that they have frozen funds in Swiss banks amid a probe into people linked to 1MDB on suspicion of corruption and money laundering.

"The Office of the Attorney General of Switzerland (OAG) has frozen assets amounting to several tens of millions of US dollars on Swiss bank accounts," an OAG spokeswoman said by email in response to an enquiry.

"At this early stage of the procedure, the OAG is analysing and consolidating evidence. The OAG is already in contact with the Malaysian authorities. International cooperation with foreign countries, in particular with Malaysia, will probably be necessary to establish the facts," she added.
