Jakarta – The Corruption Eradication Commission (KPK) grilled active and former leaders of the House of Representatives' budget committee on Tuesday in connection to a graft scandal surrounding the disbursement of the 2011 Regional Infrastructure Adjustment Fund (DPID).

The committee's deputy chairman, Olly Dondokambey of the Indonesian Democratic Party of Struggle (PDI-P), as well as his former fellow deputy Mirwan Amir of the Democratic Party, were questioned by KPK investigators in connection to Golkar Party politician Fahd El Fouz, who has been named a suspect in the case, KPK spokesman Johan Budi SP said. Both were tight lipped to journalists when asked about the KPK's interrogation.

On Monday, the KPK grilled former budget committee chairman Melchias Markus Mekeng of the Golkar Party and active deputy Tamsil Linrung of the Prosperous Justice Party (PKS) in connection to the same case.

Previously, Fahd testified before the Jakarta Corruption Court that the leaders of the budget committee played important roles in pushing for the allocation of the DPID funds.
