Prime Minister Najib Abdul Razak was neither named nor alleged to have committed any wrongdoing in the damning US Department of Justice (DOJ) civil suits on 1MDB, said attorney-general Mohamad Apandi Ali.

"The attorney-general expressed his strong concerns at the insinuations and allegations that have been made against the prime minister of alleged criminal wrongdoing in relation to the civil action.

"The attorney-general intends to clarify that at no point in the civil claim filed by the US DOJ is the prime minister named as a defendant or have been alleged to have committed any criminal wrongdoing," Apandi said in a statement today.

Apandi had earlier this year also cleared Najib of any criminal misconduct in two corruption cases linked to 1MDB.

The DOJ, in its suit seeking to seize assets allegedly acquired using siphoned 1MDB funds, did not name Najib.

However, the report mentions a "Malaysian Official 1" whom the report implicates of having received US$781 million of the misappropriated monies.

Malaysian Official 1 was cited as a "high-ranking official in the Malaysian government who also held a position of authority with 1MDB".
