Strategic development company 1Malaysia Development Berhad (1MDB) on Wednesday denied any of its bank accounts in Switzerland have been frozen.

"As far as 1MDB is aware, none of the company's bank accounts have 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," said 1MDB in a statement.

Earlier today, Reuters reported Swiss authorities as saying that they have frozen funds in Swiss banks amid a probe into 1MDB.

Office of the Attorney General of Switzerland (OAG) spokeswoman said, OAG has frozen assets amounting to several tens of millions of US dollars on Swiss bank accounts.

"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 by email in response to Reuters.
