KUALA LUMPUR: Pakatan Rakyat (PR) leader Datuk Seri Anwar Ibrahim today scoffed at the "suspicious" circumstances surrounding the purported Facebook death threat against his former aide and sodomy accuser Mohd Saiful Bukhari Azlan.

Commenting on the matter, Anwar said he was informed by his staff that the person had commented on the Facebook page and removed the comment shortly after but the screen capture of the posting had remarkably made its way to Saiful's email "in a short time".

"It can't be that they (the police) don't know who sent the email. Investigate lah," Anwar said, when met after his sodomy trial at the Kuala Lumpur High Court today.

When asked if he had known about the purported death threat posted on his Facebook fan page, Anwar remarked, "My Facebook page has thousands (of followers), how would I know?"

"He (Saiful) is fully monitored by an effective police team. Whereas I am only monitored by Azizah only," Anwar quipped, while gesturing to his wife and Parti Keadilan Rakyat (PKR) President Datuk Seri Dr Wan Azizah Ismail, who was standing beside him.

Saiful on Tuesday lodged a police report on the threat against his life at the Sentul district police station, claiming that he was informed of the death threat on Monday via email from an unknown person.

The 24-year-old told reporters Tuesday that the email came with an attachment of a screen capture of the purported posting on Anwar's Facebook fan page showing a comment left by a Anaz Zahari who allegedly wrote in Bahasa Malaysia, "To all friends, whoever knows or meets Saiful Bukhari Azlan anywhere, you are obliged to kill him using any method for the sake of mankind's peace".

Saiful last week testified, alleging that he was sodomised by the former deputy prime minister on June 26, 2008 at the Desa Damansara condominium in Bukit Damansara here.
