KUALA LUMPUR - Malaysians want to know if the sex videos involving former Parti Keadilan Rakyat (PKR) youth chief Haziq Aziz and implicating Economic Affairs Minister Azmin Ali is genuine, PKR president Anwar Ibrahim said on Tuesday (July 16).

They also want to know who was behind the videos that surfaced last month and have since gone viral.

The Sun Daily newspaper quoted Datuk Seri Anwar as telling reporters on Tuesday: "I leave the investigation to the police. But it has to be established if the videos are genuine, and who is the mastermind behind the spread of the videos."

"The people want answers for these two questions," he said.

Mr Anwar's comments came as the police said they were widening their investigation into the lewd video clips, including looking into the possible involvement of a state assemblyman.

The police on Sunday night arrested six people - including Mr Haziq and other PKR members - to assist in the investigation into the spread of the videos.

The six are being investigated under Section 377B of the Penal Code, which punishes unnatural sexual relations, and Section 233 of the Communications and Multimedia Act, concerning abuse of network facilities. All are being remanded until Saturday.

Police chief Abdul Hamid Bador said on Tuesday police were investigating the possibility that those arrested were connected to the state assemblyman. "We are investigating that possibility along with other aspects," he was quoted telling reporters by The Star.

CID director Huzir Mohamed also said the police had received a report from CyberSecurity Malaysia on the identities of the two men in the sex videos but did not provide details.

Mr Haziq has confessed to being one of the two men involved in sexual acts in the videos, and had claimed the other was Datuk Seri Azmin. Mr Azmin has denied any involvement in the videos, dismissing the scandal as a "nefarious plot" to destroy his political career.

Mr Haziq was previously detained by police for questioning on June 14, but released the next day.

Following his allegations, Mr Haziq was sacked as the principal private secretary to a deputy minister on June 20. He was later expelled from the PKR on July 3 for violating the party's code of ethics.
