KUALA LUMPUR - A MALAYSIAN court on Wednesday ordered the exhumation of the body of an opposition aide who fell to his death from anti-graft offices where he was being questioned, his family's lawyer said.

The coroner's court order will allow a second autopsy of Teoh Beng Hock's remains, assisted by prominent Thai pathologist Porntip Rojanasunan, lawyer Gobind Singh said.

Ms Porntip last month told an inquest into Teoh's mysterious death that the 30-year-old aide may have been strangled and beaten before he died.

The flamboyant expert, well known for challenging authorities in her home country, said there was an 80 per cent chance that 30-year-old Teoh was murdered and just a 20 per cent chance of suicide.

Mr Singh said Ms Porntip would not be conducting the new autopsy but would assist Malaysian medical examiners in the task.

Teoh's crumpled body was found on July 16 on the roof of an adjacent building after he had undergone questioning on the 14th floor of the Malaysian Anti-Corruption Commission (MACC) until the early hours of the morning. He was not accused of any crime, but was being questioned as part of a probe into the opposition-held Selangor state government. -- AFP
