Inspector-General of Police Razarudin Husain said the investigation papers were submitted to the AGC on Jan 15.

“The investigation papers were sent back (while awaiting the completion of forensic reports),” he said.

The police had initiated an investigation under Section 500 of the Penal Code and Section 233 of the Communications and Multimedia Act 1998 against Khairy concerning his statement about the existence of additional documents purportedly allowing former prime minister Najib Razak to serve the remainder of his prison sentence under house arrest.

Khairy’s statement was recorded on Jan 13 by the special crime investigation unit of the Bukit Aman criminal investigation department at Studio Keluar Sekejap in Bukit Damansara.

On Jan 10, Suraya Yaacob, political secretary to law and institutional reform minister Azalina Othman Said, and Nor Azrina Surip, political secretary to federal territories minister Dr Zaliha Mustafa, filed police reports against Khairy in Putrajaya and Sentul, respectively.

According to copies of the police reports, Suraya and Nor Azrina claimed that Khairy’s statement involving the two ministers was false, defamatory, misleading and caused public distress, potentially jeopardising national security.
