KUALA LUMPUR, MALAYSIA - Police have interviewed Mohd Saiful Bukhari Azlan who accused de facto opposition leader Datuk Seri Anwar Ibrahim of sodomising him.

It is learnt a task force set up to investigate the allegation interviewed the 23-year-old former aide to Anwar on Monday, and immediately followed up on his information, including visiting and investigating the alleged crime scene, a condominium in Damansara.

A police forensic unit was seen at the condominium for almost five hours.

Deputy Inspector General of Police Tan Sri Ismail Omar confirmed police had interviewed Mohd Saiful, but declined to divulge details.

'We need to be fair to all parties concerned and we assure the public that we will conduct a thorough investigation into the matter,' he said.

Ismail also said police had yet to receive any report from Anwar, his family members or his agents with regards to the alleged threat on his life.

'How can we investigate who, when, where and what the threat is all about if there is no police report lodged?' he said.

Saiful had on Saturday lodged a police report alleging Anwar had sodomised him at a condominium in Damansara last Thursday.

He was admitted to the hospital here for a medical examination and is under police protection.

On Sunday morning, Anwar fled to the Turkish Embassy here, seeking shelter after he had received death threats.
