Ina Parlina, Jakarta – Adang Daradjatun, a Prosperous Justice Party (PKS) lawmaker and former National Police deputy chief, claims he had never known of his wife Nunun Nurbaeti's involvement in a high-profile central bank case until she was summoned.

"I told investigators that I first knew about the case when my wife was first summoned by the KPK [Corruption Eradication Commission]," Adang told reporters after being interrogated at the KPK headquarters on Tuesday.

Adang underwent a two-hour KPK questioning session, his first so far in the Bank Indonesia vote-buying case.

The case has sent at least 33 former and current lawmakers to prison for accepting bribes paid to swing votes for Miranda Swaray Goeltom's election as Bank Indonesia deputy governor in 2004. The KPK, however, has not yet named the mastermind behind the case or the ones who funded it.

Adang was summoned as a witness for his wife, a suspect in the case who allegedly served as a go-between distributing Rp 24 billion (US$2.6 million) in form of 480 traveler's checks worth Rp 50 million each to lawmakers at the House's financial affairs commission.

Nunun dodged both KPK questioning sessions and Jakarta Corruption Court subpoenas, using her "severe memory loss" as an excuse to flee in 2010 to Singapore for a medical treatment. (mtq)
