"It can be said that the handling of investigation into the case is almost 90 percent complete. It is quite comprehensive," Prasetyo stated at the National Police Headquarters, Jakarta, Tuesday.
Prasetyo revealed that the results of the joint team's investigation will be delivered by the Indonesian Police along with three related institutions.
"It will be delivered together with the National Human Rights Commission, the National Police Commission (Kompolnas), and the Indonesian Ombudsman," he remarked.
Prasetyo noted that the investigation had yet to reach a stage wherein the mastermind behind the demonstration leading to the riots could be uncovered.
"On-field proof should be given first priority and high preference," he affirmed.
Prasetyo was also reluctant to speak at length on the reasons behind the deaths of nine riot victims.
"Later, the fact will be conveyed by the team. All (facts and data) have been gathered, so waiting for the team first," he stated.
Prasetyo voiced the National Police's readiness to release the results of the investigation to the public. However, his side yet awaits the readiness of the three other institutions.
"From the National Police Headquarters, it is ready. It later depends on the National Human Rights Commission, ORI (the Indonesian Ombudsman), and Kompolnas. They have their own operational standards," he added.
