Local artiste groups have taken aim at a Singaporean comedy show for allegedly mocking Prime Minister Najib Abdul Razak.

They took issue with Channel 5's 'Ok Chope' programme in which a panel of comedians were asked to complete the headline of a news story involving Najib.

The panel, comprising Sam See, Najip Ali, Rishi Budhrani and Mike Kassim offered various tongue-in-cheek answers.

However, Persatuan Seniman Malaysia secretary-general Hafiz Nafiah has threatened to lodge a police report.
