Prime Minister Najib Abdul Razak should call for an independent probe over police conduct in the case of murdered Mongolian national Altantuya Shaariibuu.

DAP parliamentarian Gobind Singh Deo said the probe will determine whether the police had properly investigated the motive in the case.

"I call upon the prime minister to direct the set-up of an independent team to probe this matter," Gobind said in a statement.
