The Malaysian Anti-Corruption Commission (MACC) has arrested a Petronas employee over suspected graft.

The national oil company confirmed this in a statement to the media today.

Petronas said the arrest followed an internal investigation on the employee conducted by Petronas, which later reported the case to the commission.

"Petronas does not condone nor tolerate any form of misconduct among its employees and contractors and is extending its fullest cooperation to MACC to further assist in their investigation if necessary," the statement said.

Petronas added that it has been working closely with MACC since 2012 to curb and prevent corruption and misconduct, not just among employees within its group of companies but also among contractors and third-party service providers. -- BERNAMA
