The marathon raid on former prime minister Najib Abdul Razak's house on Jalan Langgak Duta in Kuala Lumpur should be carried out in a more humane manner, Abdul Rahman Dahlan said.

The former minister under Najib's administration said this in a tweet today.

"The raid of DS Najib's house in the middle of the night - there are more humane ways to do the investigation. Dignity, not humiliation. Of course, he can be investigated. No problem. But a little respect, please. He is our ex-PM after all," Rahman posted.

This was in reference to the ongoing police raid on Najib's residence in Taman Duta, beginning last night, during which several boxes of handbags and personal belongings were reportedly carted away.

According to reports, several other properties in the Klang Valley, linked to the former prime minister, were also raided.

The night raid and the might of police force displayed during the action have even courted flak from some Pakatan Harapan lawmakers as well.

Permatang Pauh MP Nurul Izzah Anwar and her Shah Alam counterpart Khalid Samad said that being former victims of "dawn raids" themselves, such practices were wrong.

However, Prime Minister Dr Mahathir Mohamad has denied police high-handedness in the matter, saying the raid followed the police's standard operating procedures and he had no intention for the police to "torture anyone.

'Is Malaysia better post-May 9?'

Meanwhile, in a Facebook post, Umno information chief Annuar Musa questioned whether the country was heading towards betterment after the regime change on May 9. 

Referring to the raid, Annuar said: "What I'm witnessing now reminds me how DSAI (PKR de facto leader Anwar Ibrahim) was arrested, treated, and shamed, as that during that time (in 1998, his first sodomy case), we stayed in the same neighbourhood in Bukit Damansara, KL. 

"Today, the same thing is happening again (in Najib's house). In fact, it goes against what the religion says about Ramadhan. 

"It's business as usual. While one (Anwar) has come out to talk about injustice and tyranny after 20 years of "torture", history is repeating in another (Najib), in fact, this could be even worse!" Annuar wrote.
