The police are expected to record a statement from former law minister Zaid Ibrahim at the Bukit Aman police headquarters in Kuala Lumpur tomorrow.

Zaid told Malaysiakini that he believes this is related to the tweets he posted on Dec 5 on Selangor ruler Sultan Sharafuddin Idris Shah.

However, he said the police did not tell him which law he was being investigated under.

"No, I don't know (which law), I just got a message (for me) to go there. It doesn't matter, I will go and answer the questions," said the DAP member.

"I think the police must investigate because a lot of people have lodged complaints and it has become a public issue.

"The police have to check whether I breached the law, so they have to listen to my explanation. I think it is okay," he added.

Zaid maintained that he had done nothing wrong and there was no element of sedition in his tweets.

In an interview with The Star published on Dec 5, the Selangor ruler had said that former prime minister Dr Mahathir Mohamad's anger could raze the nation.

Sultan Sharafuddin also described Mahathir as someone with an “inferiority complex” and “deep hatred”.

Zaid then tweeted that the Selangor ruler “should careful with his words” and that “no one is immune when the country burns”.

His comment courted flak from Umno leaders, who, among others, torched cardboard cutouts of the former minister. The sultan himself rebuked Zaid for being rude.

Previously, inspector-general of police Mohd Fuzi Harun confirmed that Zaid is being probed under the Sedition Act 1948. He is also being investigated under the Communications and Multimedia Act 1998.

Last week, Zaid, when asked if he would apologise to the ruler, said he was merely following the Islamic tradition of offering advice to the rulers.
