Novianti Setuningsih – On Tuesday, Corruption Eradication Commission (KPK) investigators were locked inside of the National Police compound on when Police refused to let the KPK seize boxes of evidence in the graft-tainted purchase of driving simulators.

But the police eventually allowed the commission to leave, and the evidence in question is now under heavy and constant guard at the KPK building, with both police and KPK officers standing a 24 hour watch over the contentious boxes. The National Police have reportedly assigned their provost to watch over the evidence at the commission office.

"[Police] members have been here since the case appeared," said one KPK security member on Friday of the batik clad National Police marshals. He added that just one official of the KPK has the key to the heavily guarded boxes.

Bambang Widjojanto, deputy chairman of KPK, said on Thursday that the evidence belongs to the KPK. "We have the decision of the court issued on July 30." Bambang said. "The evidence that has been confiscated is under the authority of KPK."

Bambang added that the KPK is assessing the evidence to determine what they need to build their case. He also said that other legal institutions who wish to borrow the evidence should first send a letter to KPK.

"There should be request to use the evidence, then there's no problem," Bambang said. "But the most important thing is all the evidence is with the KPK; all sides are securing it."

The KPK named two police generals as suspects in the driving simulator graft case, including Insp. Gen. Djoko Susilo, the former director of National Police Traffic Corps (Korlantas) and current Police Academy governor, as well as Korlantas current deputy chief, Brig. Gen. Didik Purnomo.

Djoko allegedly received Rp 2 billion ($212,000) in a kickbacks to award a contract to buy more than 1,200 driving simulators to metal company Citra mandiri Metalindo Abadi.
