Lim Guan Eng is wondering if Malaysia is now a police state, where the police cannot be questioned or reprimanded.

The DAP secretary-general was responding to inspector-general of police Khalid Abu Bakar warning DAP lawmaker Teo Nie Ching against politicising investigations.

Lim said the Kulai MP was merely exercising her duty in urging the police to probe red shirts leader Mohd Ali Baharom over his threat to Bersih chairperson Maria Chin Abdullah.

"For airing her view, Teo received a stern warning not to meddle or politicise police matters.

"I cannot understand what it is that cannot be interfered or politicised. An MP is the representative of the people, and has the right to voice out.

"Should MPs just remain silent when witnessing threats and other crimes?" he asked in a media statement.

Lim also questioned why police moved against Jelutong MP Jeff Ooi for making an allegedly insensitve tweet about the passing of PAS spiritual leader Haron Din; but did not act against Langkawi MP Nawawi Ahmad for linking the Agong to the controversial Malaysian Official 1 (MO1).

“Is making an ‘insensitive’ tweet, or someone being a loudmouth a major crime in Malaysia now?

“What Nawawi did was far worse. Nawawi had linked MO1, who was accused by the US Department of Justice of being involved in the theft of 1MDB funds, to the Agong.

“But no action was taken against the Umno MP who was worse than a loudmouth.”

Khalid had previously said that police would question Nawawi over his remarks, but there has been no update on this matter as yet.

Nawawi had apologised for the incident, but maintained his words were taken out of context.

Lim also took issue with the police taking no action against former Perkasa leader Zulkifli Noordin, who made an insensitive tweet when Karpal Singh died in an accident.

Zulkifli had on Karpal’s death in 2014, said it was an act of God to remove an obstacle for Kelantan to implement hudud.

Lim said the lack of action against Nawawi and Zulkifli showed that Khalid practiced double standards.
