Jakarta – The Attorney General's Office (AGO) said Monday it will return the case file of Maj. Gen. Muchdi Purwopranjono, a suspect in the 2004 murder of human rights activist Munir Said Thalib, to police.

"We have found the dossier incomplete and will return it to police before July 21," said M. Ismail, the AGO pre-indictment director at the deputy attorney general for crimes office.

He said the case file lacked the signatures of detectives in charge and witnesses. "We informed the police on July 11, and we'll provide them a guideline on how to complete it," Ismail said.

The National Police handed over Muchdi's dossier to the AGO on July 8, after completing its investigation of Muchdi, who has been detained since June 19.

Muchdi, a former State Intelligence Agency (BIN) deputy chief, was mentioned by BIN agent Budi Santoso in a written statement that was read out during the court trial of Garuda pilot Pollycarpus Budihari Priyanto, who was later sentenced to 20 years imprisonment for the same murder.
