Home Minister Ahmad Zahid Hamidi said he will discuss the recent call made by former premier Dr Mahathir Mohamad for Prime Minister Najib Abdul Razak to be arrested under the Security Offences (Special Measures) Act (Sosma).

Zahid said it was the prerogative of the police (whether to investigate the matter).

“I haven’t discussed the matter with the inspector-general of police (Khalid Abu Bakar) yet.

“I will discuss it (with him) depending on how strong the evidence is,” he said.
