"I was made to understand the investigation is under Section 4(1) of the Sedition Act and Section 233 of the Communications and Multimedia Act.
"I am ready to give my utmost cooperation to the police. Berani kerana benar," he said in another tweet.
According to the police, the questioning is set to take place at 2.30pm today.
In the Al Jazeera interview, Syed Saddiq had criticized Prime Minister Muhyiddin Yassin for allegedly colluding with "kleptocrats" from the BN-era government to remain in power, despite having challenged them when the premier was part of the former ruling coalition, Pakatan Harapan.
The former minister was answering a question on Muhyiddin's changing of allegiance and ascent to power.
Watch the interview below:
It is worth noting that Syed Saddiq was among those sacked from Bersatu (he was the youth chief), along with the likes of its former chairman Dr Mahathir Mohamad, ex-deputy president Mukhriz Mahathir, as well as Maszlee Malik.
Syed Saddiq is the second MP aligned to PH that have been recently hauled up by the cops.
Former deputy women, family and community development minister Hannah Yeoh was previously called up for questioning over a tweet in March, which had questioned the future of the five-year National Strategy Plan to end child marriage, under the current government.
Saya telah dipanggil oleh Bukit Aman untuk memberi keterangan bagi siasatan mengenai tweet ini. Sekarang ini, tanya soalan pun tak boleh. Sidang Parlimen bulan Mei juga tak diberi peluang tanya soalan. Roadmap ini hasil kerja kuat pentadbiran bawah PH @drwanazizah. pic.twitter.com/M72pb5p1I6
The Segambut MP is scheduled to meet the cops in Bukit Aman next Tuesday.
Yeoh is being investigated under Section 505 of the Penal Code, which pertains to statements conducing to public mischief, as well as Section 233 of the Communications and Multimedia Act 1998, which concerns the improper use of network facilities.
