The Malaysian Anti-Corruption Commission (MACC) said it accepted the decision by the appellate court in setting aside the coroner’s open verdict in the inquest of Teoh Beng Hock.

In a statement today, MACC said it will leave it to the police to conduct investigations into Teoh's death and the Attorney-General to decide whether anyone should be prosecuted.

“The MACC today pledged to give full cooperation and ensure justice is done."

“MACC hopes that closure on the case can be obtained as soon as possible.”

On Friday, the Court of Appeal overturned the open verdict on the 2009 death of Teoh, then a DAP political aide to Selangor executive councillor Ean Yong Hian Wah.

The court also ruled that his death was resulted from an unlawful act by a person or persons unknown.

The three-man panel, headed by Justice Datuk Mohamad Ariff Md Yusof, was unanimous in its decision and called for a further probe into the death by not excluding MACC officers who were involved in Teoh’s arrest and investigation.

The two other judges were Datuk Mah Weng Kwai and Datuk Dr Hamid Sultan Abu Backer.

All three judges came up with their own written judgement.

Justice Mah, in his judgment, ruled that Teoh's was a custodial death while under the detention of MACC officers.

He said Teoh was called to the MACC office as a witness and subjected to questioning until the early hours of the morning, which clearly showed that his rights had been violated.

Mah ruled out the possibility of Teoh having committed suicide, saying the handwriting on a suicide note alleged to have been Teoh's could not be verified by an expert as his.

Furthermore, Teoh's conduct prior to the incident clearly showed that he was in a right frame of mind and was busy making arrangements for his wedding, he said.

Mah also referred extensively to the views of two experts in ruling out suicide as a possibility of death as suggested by counsel representing the MACC during the inquest.

He referred to the views of experts Dr Pornthip Rojanasunand and Dr Peter Venezis in the notes of the inquest that Teoh might have been strangled by someone based on the injuries on his neck.

"This might have resulted in him losing consciousness, and both (experts) believe he was still alive when he fell from the 14th floor of the building and I agree with them," Mah said, according to a Bernama report.

He also questioned the conduct of the MACC officers who had interrogated Teoh and urged police to carry out further investigation on who actually harmed the victim and urged them (police) not to exclude all those MACC officers who were last seen with Teoh.

Teoh was found sprawled on the fifth floor landing of Plaza Masalam in Shah Alam, where the MACC headquarters was formerly located, on the morning of July 16, 2009.

He was 30-years-old.

Meanwhile, Teoh’s young sister Lee Lan said the appellate court's decision was just the beginning of the family’s long fight for the “truth” behind her brother’s mysterious fall to death, Malay Mail reported.

“Today, after waiting five years for justice for us, the court decided that Beng Hock was persecuted, killed, tortured by persons who are still unknown, but including MACC officers,” she was quoted saying.

The 34-year-old auditor said she hopes the police, Attorney General will take immediate action and arrest the MACC officers involved based on the latest court decision.
