National Police Chief Gen. Timur Pradopo says they are auditing the "pocket money" received from American mining giant Freeport-McMoRan's Indonesian unit to help provide security at the Grasberg mine in Papua.

Despite the ongoing audit, Timur told Detik.com that "there is no violation."

Lawmakers and activists demanded an immediate investigation into where the Freeport millions have gone after Timur admitted that the joint security force operating in the troubled region was paid $14 million in "pocket money" by Freeport for helping to provide security.

The fact Freeport pays Indonesian security forces directly is not new, however. On Sunday, Timur said the Corruption Eradication Commission (KPK) as well as Supreme Audit Agency (BPK) could also audit the police's books for "the sake of accountability and truth."

The police are perceived to be one of Indonesia's most corruption-prone institutions.
