Sarawak Report claims that law enforcers in United States, United Kingdom, and Switzerland are also probing into materials leaked from the 1MDB and PetroSaudi joint venture.

In a press statement yesterday, Sarawak Report said that the 'chain of events' after former PetroSaudi employee Xavier Justo leaked the material to them in February, showed that the material had separately gone to other countries and their law enforcers as well.

"The chain of events shows why Sarawak Report could not have tampered with the material, because at the same time it was acquired, it also went separately to The Edge and the Sunday Times…and was then passed on to regulators and law enforcers in the United States.

"The material has now also been offered to regulators and law enforcers in the UK and Switzerland and also by The Edge to law enforcers in Malaysia," said the statement.

Sarawak Report admitted that it had introduced Justo ( photo ) to the managers of The Edge in February at a meeting at the Fullerton Hotel, Singapore.

Three copies of the materials were then made – one handed to Sarawak Report , one to The Edge and another for safekeeping.

Sarawak Report then had to share their copy with the Sunday Times , as they did not have the computer experts to decrypt the material’s data before using it to publish their stories.

“Meanwhile, The Edge had to put its own computer experts onto their copy of the same material back on the other side of the world in Singapore. They too finally managed to open the file and completely separately have come to exactly the same conclusions about the nature of the PetroSaudi deal,” the statement added.

Detained for blackmail

Justo, a former executive of PetroSaudi, is being detained in Thailand for attempting to blackmail the firm with the stolen documents.

He is also said to be the source of the leaked documents and email communiques.

In an exclusive interview with the Singapore Straits Times , Justo claimed that he was not paid as agreed and was told of plans to tamper with the documents.

Sarawak Report also claims that the data which was shared to several corners of the world is now being used in the investigations, proving what they published is not gibberish.

“If all we had written was a whole lot of nonsense, the investigators from the Task Force and the PAC would have thrown in the towel weeks ago and declared us mischievous liars.

"Instead, they have dug up piles more incriminating evidence and issued warrants of arrest to 1MDB executives who have start fleeing like flies,” the statement said.
