Farouk Arnaz – National Police on Thursday said they would provide support for the Attorney General's Office to review the controversial murder case of renowned activist Munir Said Thalib.

Former top intelligence official Muchdi Purwoprandjono was acquitted of charges he ordered the killing.

"We will fully submit to the attorney general and, if necessary, we will help. The principal authority is with the prosecution team," National Police Chief Gen. Bambang Hendarso Danuri told reporters.

Asked if police needed to set up a new team to collect evidence for the case review, Bambang said: "No. It's not necessary to set up a new team. If the attorney general asks for it, we will provide assistance," he said.

The mystery behind Munir's murder remains unsolved despite the fact that he was killed five years ago.

Prosecutors accused Muchdi of ordering the murder to avenge his ouster from the top post of the Army's Special Forces (Kopassus) in 1998, arguing that Muchdi was fired following fierce criticism from Munir over the alleged kidnapping of students and activists by the elite unit.

But a district court ruled on Dec. 31 last year that such a motive could not be proven and the Supreme Court upheld the acquittal in June. The only remaining legal option for the AGO is to ask for a case review. Munir died of arsenic poisoning on a Garuda flight en route to Amsterdam on Sept. 7, 2004.
