The controversial documentary produced by Al-Jazeera which was aired recently is an attempt to discredit Prime Minister Datuk Seri Najib Tun Razak, says former inspector-general of police, Tan Sri Musa Hassan.

The documentary which tried to raise new evidence in connection with the death of Mongolian national Altantuya Shaariibuu in 2006 were mere allegations without any concrete proof to link Najib in the high-profile case, he said.

"The police investigation did not show Najib, who was then deputy prime minister, was in any way, involved as there was no evidence to associate him in the case.

"I also noted that there were several allegations such as an image showing Najib having dinner with Abdul Razak Baginda, his advisor then, but it is obvious that the photograph is a fake and certain quarters are trying to sensationalise the issue," he said in a press conference here today.

Musa said although he was not in favour of any party, he decided to come out with the truth as of late, there were several fictitious news featured by the media.

In addition, he said Najib might take legal action against the media agency concerned (Al-Jazeera) if he felt he had been vilified in the documentary.

Recently, a 25-minute documentary broadcasted by Al-Jazeera, among others questioned the involvement of two police officers, Sirul Azhar Umar and Azilah Hadri who were made scapegoats and convicted of the murder of Altantuya.

On Thursday, the Prime Minister's Office in a statement stressed that Najib never knew, was never involved and had never communicated or contacted Altantuya.

Earlier, Communications and Multimedia Minister, Datuk Seri Mohd Salleh Said Keruak said everything featured in the documentary was based on hearsay and not concrete evidence.

Today, Inspector-General of Police, Tan Sri Khalid Abu Bakar said the documentary was a report based on false assumptions and the police were investigating the matter under Section 505 (b) of the Penal Code with the intent to cause fear and alarm to the public.
