Jakarta – The National Police will continue to involve the FBI in resolving the 2002 killings of one Indonesian and two American teachers in Timika, Papua – but agents won't be allowed to question the suspects.

National Police spokesman Brig. Gen. Anton Bachrul Alam said the FBI agents would not be allowed to directly interrogate suspects in the case but would continue to be informed of developments.

"In the investigation we are cooperating with the FBI and providing them information related to the case," he said at Police Headquarters in Jakarta.

Police earlier confirmed that FBI agents had given them information that led to the arrest of 12 Papuans suspected of involvement in the attack near the Grasberg Mine of PT Freeport Indonesia in Timika.

"We are aware of their more sophisticated technology (in criminal investigations)," Anton said. In comparison police in Papua had a poor communications and transportation system, he said.

Anton stressed the authority to investigate the incident was still in the hands of the National Police, and not the FBI.

"The crime took place in Indonesia and it is our duty to investigate it. We are involving (FBI agents) in the matter just to get relevant information."

It is not the first time Indonesia has involved foreign security forces in criminal investigations. In 2002, the Australian Federal Police helped their Indonesian counterparts investigate the first Bali bombings that killed 202 people, including 88 Australians.

Also on Tuesday, Patsy Spier, a survivor of the shooting and the wife of one of the Americans killed in the attack, appeared at the National Police headquarters to give her eye-witness testimony.

Spier earlier met President Susilo Bambang Yudhoyono Monday, asking him to ensure the FBI was involved in further investigations into the incident to ensure a transparent and credible process. In earlier statements Spier has said she believed the Indonesian Military could be involved in the attack.

The police are detaining eight suspects in Jakarta – among the 12 Papuans who were originally arrested in Jayapura for their alleged roles in the shooting. Four of the suspects were later freed because police lacked sufficient evidence to charge them.

One Indonesian and two American teachers were killed and 12 other passengers, including Spier, were injured when their convoy was attacked by gunmen on Aug. 31, 2002. The teachers worked for the American-owned Freeport mine.
