Jakarta – The Corruption Eradication Commission (KPK) says that it is investigation procurement projects at five universities that may be linked to the House of Representatives' budgetary commission.

KPK chairman Busyro Muqoddas said that his office had questioned I Wayan Koster, a lawmaker from the Indonesian Democratic Party of Struggle (PDI-P) who was also a member of the House's budget commission, as his testimony as a member of both affiliations was needed. "[His role in those two institutions] cannot be separated," he said on Thursday.

On Wednesday, Koster underwent KPK questioning in an investigation into dubious procurements of laboratory equipment at five universities commissioned by the Education Ministry in 2010.

The five universities are Jakarta State University (UNJ); Sriwijaya University in Palembang, South Sumatra; Jenderal Soedirman University in Purwokerto, Central Java; Sultan Ageng Tirtayasa University in Banten and University of Malang in East Java.

Busyro added that the KPK would first decide whether it was necessary to summon other members of the budget commission.

Koster once underwent KPK questioning for an investigation into a different high-profile bribery case centering on a construction project for the upcoming SEA Games. KPK questioned him as a witness in the case, in which former Democratic Party treasurer Muhammad Nazaruddin was a suspect.
