The four officers arrived at the Perdana Leadership Foundation (PLF) here at 1.34pm in two vehicles with documents for investigations.

Four lawyers, led by Haniff Khatri Abdulla, had arrived 30 minutes earlier to sit in during the recording of the former prime minister’s statement.

Speaking at a rally at Padang Timur in October, Mahathir had criticised Prime Minister Najib Razak, calling him a “descendent of Bugis pirates”.

The Selangor Royal Council subsequently called for Mahathir to be investigated under the Sedition Act or any other appropriate law over his remark.

Selangor ruler Sultan Sharafuddin Idris Shah later said that after discussions with members of the council, he viewed with utmost seriousness, anger and disappointment the speech of the Pakatan Harapan (PH) chairman, which appeared to incite the people to hate, show contempt and negatively perceive the Bugis.

The ruler had also said the allegation had directly insulted the ancestral roots of the Selangor sultanate, which was founded by the Bugis.

Haniff had previously defended the PPBM chairman,  saying that Mahathir had used the term to criticise Najib only, not the community.
