The Malaysian Anti-Corruption Commission (MACC) confirmed today it has been working with the United States (US) Federal Bureau of Investigation (FBI) in connection with the report from their Department of Justice (DOJ) on 1Malaysia Development Berhad (1MDB).

It said in a statement Friday, the two have had a long working relationship all this while.

"With regards to report from the DOJ on 1MDB, the MACC confirmed that it has collaborated with the FBI.

"This is because, the two parties have had a long working relationship before," it said.

In relation to this, MACC said, the above-mentioned cooperation is focused on the possibility of fraud and money laundering by a businessman who was said to have cheated 1MDB.

Meanwhile, on Thursday, 1MDB claimed it was not a party to the civil suit brought by the US government, as announced by its Attorney-General Loretta Lynch.

On Wednesday, Lynch told a press conference in Washington, the US DOJ was moving to seize more than US$1 billion (RM4billion) in assets allegedly tied to corruption at a state-owned investment fund.

She claimed they were the tainted proceeds of the misappropriation of billions of dollars from the scandal-tarred 1MDB.
